ABB 1SDA038306R0001 Overview

The ABB 1SDA038306R0001 is an undervoltage release accessory used with specified ABB circuit breakers. ABB documentation lists the product as a 24V DC under voltage release for the E1/6-T8 configuration.

An under voltage release is a circuit breaker accessory that monitors the control voltage supplied to the release mechanism. When the control voltage falls below the required operating condition, the release mechanism can cause the circuit breaker to open according to its design.

This function provides an additional level of control for electrical distribution and protection systems.

24V DC Under Voltage Release

The ABB 1SDA038306R0001 is specifically rated for 24V DC operation. ABB product information identifies the nominal DC supply voltage as 24V.

The 24V DC control voltage is commonly used in industrial control systems and electrical distribution equipment because it can be integrated with control circuits, monitoring systems, and protective equipment.

The control supply for the under voltage release should correspond to the rated specification of the installed component.

Under Voltage Release Function

An under voltage release is designed to respond to the condition of its control supply. The device is associated with the circuit breaker operating mechanism and provides a controlled response when the required control voltage is absent or insufficient.

This type of accessory can be used where the circuit breaker must remain dependent on an external control voltage for its operating state.

The exact operating behavior depends on the circuit breaker mechanism and the installation configuration.

E1/E6 Circuit Breaker Compatibility

ABB identifies the 1SDA038306R0001 as an E1/6-T8 under voltage release. ABB low-voltage catalogues list the component under the under voltage release accessories for T8 compact circuit breakers.

The E1/E6 designation is important when checking compatibility because ABB offers different accessories for different circuit breaker frames and generations.

The complete breaker model and accessory configuration should therefore be verified before installation.

Tmax T8 Circuit Breaker Applications

The ABB Tmax T8 is part of ABB’s low-voltage circuit breaker product range. The 1SDA038306R0001 is listed specifically as a 24V DC under voltage release for the E1/6-T8 configuration.

Within a T8 circuit breaker assembly, the undervoltage release forms part of the accessory and control mechanism rather than the main current-carrying protection element.

This distinction is important when identifying the component for maintenance or replacement.

Electrical Control Function

The under voltage release is controlled by an external electrical circuit. The 24V DC control supply is connected to the appropriate terminals of the accessory according to the circuit breaker installation instructions.

The control circuit can be incorporated into a larger electrical distribution or automation system.

Before connecting the component, the control voltage and wiring arrangement should be verified against the applicable ABB documentation.

Protection and Safety Applications

Undervoltage releases can be used in electrical systems where a circuit breaker needs to respond to a loss or reduction of control voltage.

For example, an installation may require a circuit breaker to open when the control supply is interrupted. The undervoltage release provides the mechanism required for this type of operating condition.

The actual protection strategy depends on the overall electrical system design.

Industrial Electrical Distribution

ABB low-voltage circuit breakers are used in electrical distribution systems for industrial facilities, infrastructure, commercial buildings, machinery, and other applications.

Circuit breaker accessories such as undervoltage releases expand the control functionality of the breaker and allow the breaker operating mechanism to interact with external control circuits.

The ABB 1SDA038306R0001 is one such accessory designed for specified ABB breaker configurations.

Technical Specifications

Related ABB Under Voltage Releases

ABB’s catalogues list a series of under voltage releases with different control voltages. The 24V DC version is identified by 1SDA038306R0001. Related references include 1SDA038307R0001 for 30V AC/DC, 1SDA038308R0001 for 48V AC/DC, 1SDA038309R0001 for 60V AC/DC, and additional versions for higher control voltages.

The different control-voltage versions demonstrate why the complete ABB ordering number is important when identifying an undervoltage release. Components with similar mechanical functions may have substantially different control-voltage requirements.

Control Voltage Selection

The control voltage is one of the most important selection criteria for an undervoltage release. The ABB 1SDA038306R0001 is specifically the 24V DC version.

It should not be substituted solely on the basis of physical similarity with an undervoltage release designed for another voltage.

The control circuit voltage should always be checked before selecting the accessory.

Circuit Breaker Accessory Integration

Circuit breaker accessories are installed within or around the circuit breaker operating mechanism. Their correct mechanical position and electrical connection are essential to reliable operation.

The ABB 1SDA038306R0001 is intended for the specific breaker configuration identified by its E1/6-T8 designation.

The installation should follow the appropriate circuit breaker assembly instructions.

Maintenance Considerations

Maintenance personnel can use the complete part number to identify the correct undervoltage release during inspection and component replacement.

Important identification information includes the ABB product number, rated control voltage, breaker frame, accessory designation, and physical markings on the component.

If an undervoltage release is being replaced, the control circuit should also be checked to ensure that the correct 24V DC supply is available.

Compatibility Verification

Compatibility of the ABB 1SDA038306R0001 should be verified using the complete circuit breaker model and accessory documentation.

ABB documentation specifically associates this part with the E1/6-T8 configuration.

A matching part number and correct control voltage are important indicators, but the complete breaker configuration should also be checked before installation.

Inventory Management

For industrial inventory management, the recommended record is:

• Brand: ABB
• Part Number: 1SDA038306R0001
• Description: Under Voltage Release 24V DC E1/6-T8
• Rated Control Voltage: 24V DC
• Application: ABB Low-Voltage Circuit Breakers
• Compatible Series: E1/E6 and Tmax T8

Using the complete ordering number helps prevent confusion with the other ABB undervoltage-release variants listed in the same product family.

Product Identification for Online Catalogues

A suitable technical product name for an industrial product catalogue is:

Part Number Verification

The exact part number is 1SDA038306R0001. ABB product catalogues list this ordering number as the 24V DC under voltage release for the E1/6-T8 configuration.

Product data also identifies the EAN/GTIN as 8015644383060.

These identification details can be used to distinguish the component from other ABB under voltage releases with different control voltages.

System Installation

When installing an ABB 1SDA038306R0001, the circuit breaker should be isolated from the relevant electrical supply and the installation procedure should follow the applicable technical instructions.

The 24V DC control circuit should be connected according to the specified wiring arrangement. Mechanical installation should also be checked to ensure that the accessory is correctly positioned within the circuit breaker assembly.

Industrial Application

The ABB 1SDA038306R0001 is suitable for industrial low-voltage electrical distribution applications where an undervoltage release is required on a compatible ABB circuit breaker.

The accessory can provide a controlled circuit-breaker response to the condition of the external 24V DC control supply.

This type of functionality can be incorporated into electrical distribution, machinery control, industrial facilities, and other low-voltage power systems.
