ABB GCE7004590P0115 Overview

ABB GCE7004590P0115 is an electromagnetic opening coil used within the operating mechanism of compatible medium-voltage circuit breakers. Its electrical function is to convert a control signal into mechanical actuation.

In ABB ADVAC Model 3 documentation, GCE7004590P0115 is listed as an open coil with a 125 VDC rating and a quantity of one per breaker. :contentReference[oaicite:2]{index=2}

ABB-related product information also identifies the component as “SHUNT RELEASE OFF Y2, 110V DC/AC” and describes the associated product as an L32 solenoid for VD4 classic equipment. :contentReference[oaicite:3]{index=3}

Opening Coil Function

An opening coil, commonly referred to as a trip coil or shunt release, is used to initiate the opening operation of a circuit breaker when an electrical trip command is received.

When the coil is energized, its electromagnetic field produces movement in the associated release mechanism. This movement allows the breaker mechanism to release the stored mechanical energy and move the main contacts toward the open position.

The exact mechanical sequence depends on the circuit breaker design and operating mechanism.

Shunt Release OFF Y2

GCE7004590P0115 is identified in ABB-related product information as the OFF Y2 shunt release. The Y2 designation identifies the opening or shunt-release function within the associated breaker control architecture. :contentReference[oaicite:4]{index=4}

The opening coil is therefore different from the closing coil. The closing coil initiates the closing sequence, while the opening coil provides the electrical actuation required for breaker opening.

110-125 VDC/AC Control Rating

The product designation associated with GCE7004590P0115 identifies a 110-125 VDC/AC control range. ABB’s ADVAC Model 3 documentation specifically lists the component as an OPEN COIL, 125VDC. :contentReference[oaicite:5]{index=5}

The control voltage must be matched to the existing breaker control circuit. A coil intended for a different voltage configuration should not be substituted without confirming electrical compatibility.

For maintenance identification, the complete product number should be retained together with the voltage marking found on the actual component.

Application in ADVAC Model 3

ABB’s ADVAC Model 3 installation and maintenance documentation lists GCE7004590P0115 among the electrical control renewal parts and accessories. The documented description is OPEN COIL, 125VDC. :contentReference[oaicite:6]{index=6}

The component is therefore relevant to the opening function of compatible ADVAC Model 3 circuit breakers and their associated operating mechanisms.

The breaker model, control voltage and mechanism configuration should be verified before selecting the component for a particular installation.

Application in VD4 Circuit Breakers

ABB-related product information identifies GCE7004590P0115 with VD4 classic medium-voltage vacuum circuit breaker equipment and describes it as a shunt release OFF Y2, 110V DC/AC. :contentReference[oaicite:7]{index=7}

Other equipment records also identify GCE7004590P0115 as an opening coil for VD4 40.5 kV equipment. :contentReference[oaicite:8]{index=8}

Because VD4 circuit breakers are available in multiple configurations, the exact breaker type and operating mechanism should be checked against the original part number.

Vacuum Circuit Breaker Operating Mechanism

A medium-voltage vacuum circuit breaker contains both electrical and mechanical components. The vacuum interrupter performs the primary switching function, while the operating mechanism moves the contacts between the open and closed positions.

The ABB GCE7004590P0115 opening coil is part of the electrical actuation system controlling this mechanism.

When the coil receives the correct trip command, it operates the corresponding release mechanism and initiates breaker opening.

Electrical Control Circuit

The opening coil is connected to the circuit breaker control system. A trip signal can originate from protection relays, control switches, remote commands or other protection and automation equipment.

Once the trip circuit is energized and the required conditions are satisfied, the opening coil operates the breaker mechanism.

Auxiliary contacts and interlocking circuits may also provide status feedback and control logic around the opening operation.

Protection Relay Interface

In a medium-voltage switchgear system, the opening coil can form the final electromagnetic actuator between the protection system and the mechanical breaker mechanism.

For example, when a protection relay detects an electrical fault, its trip output can energize the breaker opening circuit. The opening coil then actuates the mechanical release mechanism.

This arrangement allows protection equipment to operate the circuit breaker without directly moving the mechanical switching assembly.

Difference Between Opening and Closing Coils

The opening and closing coils have different functions within the breaker mechanism. ABB documentation lists GCE7004590P0105 as a CLOSE COIL, 125VDC, while GCE7004590P0115 is listed as an OPEN COIL, 125VDC. :contentReference[oaicite:9]{index=9}

Although both components may use similar electromagnetic operating principles, their mechanical functions and installation positions are different.

The complete ABB part number should therefore be checked before replacement.

Technical Specification Summary

Mechanical Actuation

The opening coil does not directly carry the primary circuit current. Instead, it operates the mechanical release mechanism of the circuit breaker.

This separation allows a relatively low-power control circuit to command the opening of a medium-voltage power circuit.

The exact mechanical linkage varies according to the breaker design and operating mechanism.

Maintenance Considerations

Maintenance of GCE7004590P0115 can include inspection of the coil body, electrical terminals, control wiring, mounting position and associated mechanical linkage.

If the circuit breaker fails to open after a valid trip command, the opening coil is one of several components that may need to be checked.

The control supply, protection relay output, wiring, auxiliary contacts, interlocks and mechanical mechanism should also be considered during troubleshooting.

All work on medium-voltage switchgear should be carried out using the applicable isolation and electrical safety procedures.

Opening Coil Troubleshooting

If an opening command is issued but the breaker does not trip, the first checks normally involve confirming that the correct control signal reaches the opening circuit.

The voltage at the coil terminals can then be compared with the specified control voltage. If the correct voltage is present but the coil does not operate, the coil and mechanical release mechanism may require further inspection.

A complete breaker control schematic should be used when troubleshooting the circuit.

Compatibility Considerations

Before selecting ABB GCE7004590P0115, the following information should be verified:

• Complete ABB product number
• Opening coil or shunt release function
• 110-125 VDC/AC control rating
• 125 VDC breaker control voltage
• Breaker model
• Operating mechanism type
• Coil mounting arrangement
• Electrical terminal configuration
• Control circuit wiring

The original breaker identification and installed coil marking should be compared before replacement.

Related Coil Configurations

ABB’s ADVAC Model 3 documentation lists several opening coil variants for different control voltages. GCE7004590P0115 is the 125 VDC open coil, while GCE7004590P0116 is listed for 250 VDC, GCE7004590P0113 for 48 VDC and GCE7004590P0111 for 24 VDC. :contentReference[oaicite:10]{index=10}

This demonstrates why the complete part number is important when identifying a circuit breaker coil.

The voltage suffix configuration should always be matched to the control system of the breaker.

VD4 Application

GCE7004590P0115 is also identified as an ABB shunt release OFF Y2 for VD4 classic circuit breakers. The associated product information describes the component as an L32 solenoid for 110-125 VDC/AC applications. :contentReference[oaicite:11]{index=11}

This makes the part relevant to maintenance and replacement of compatible ABB VD4 vacuum circuit breaker operating mechanisms.

Product Identification for Inventory

For industrial inventory records, the recommended product description is ABB GCE7004590P0115 L32 110-125VDC/AC Opening Coil.

The alternative description ABB Shunt Release OFF Y2 110-125VDC/AC can also be retained as a technical identification reference.

The ABB product number should remain the primary identifier because similar GCE7004590P01xx components have different functions and voltage ratings.

Application in Switchgear

The GCE7004590P0115 opening coil is intended for integration into the electrical control section of compatible medium-voltage switchgear.

It works together with the circuit breaker operating mechanism, protection system, auxiliary contacts and control wiring to provide electrically initiated breaker opening.

The component is therefore an important part of the breaker control architecture even though it is not part of the primary current-carrying circuit.
