ABB 2CDS200936R0001 S2C-H11L Auxiliary Contact for S200 Circuit Breakers

The product identification 2CDS200936R0001 corresponds to the S2C-H11L auxiliary contact. ABB documentation identifies this component as an auxiliary contact for S200 family miniature circuit breakers. Its contact configuration is 1 normally open contact and 1 normally closed contact, allowing the operating position of the circuit breaker to be transferred to an external monitoring or control circuit.

Product Overview

The ABB S2C-H11L is part of the accessory system used with ABB modular DIN-rail protection devices. Unlike the circuit breaker itself, the auxiliary contact does not provide the primary overcurrent protection function. Instead, it provides an additional electrical signal that can be used by a control system, monitoring circuit, signaling circuit, or electrical panel interface.

When installed with a compatible S200 miniature circuit breaker, the auxiliary contact follows the position of the associated switching device. This makes it possible for an external circuit to determine whether the connected breaker is in the corresponding operating state. Such feedback can be useful in distribution boards, control cabinets, automation panels, and other low-voltage installations where circuit status needs to be monitored.

ABB S2C-H11L Identification

The product can be identified using several related designations. The ABB order code is 2CDS200936R0001, while the extended product type is S2C-H11L. The S2C designation identifies the accessory family, while H11L identifies the particular auxiliary contact configuration and mounting arrangement.

Contact Configuration

The 2CDS200936R0001 uses a 1NO/1NC contact arrangement. NO refers to normally open, while NC refers to normally closed. This configuration gives the external control system two complementary contact states that can be used for circuit status indication.

The auxiliary contact is particularly useful when the circuit breaker needs to provide a feedback signal to another part of an electrical system. Depending on the control circuit design, the available normally open and normally closed contacts can be incorporated into indication circuits, relay logic, PLC input circuits, alarm circuits, or other monitoring arrangements.

The auxiliary contact should be distinguished from other S2C accessory versions. ABB also provides auxiliary contacts with different contact configurations and mounting positions. For this reason, the complete order code should be checked when selecting a replacement or designing an installation.

Compatibility with ABB S200 Circuit Breakers

ABB identifies the S2C-H11L as an accessory for compatible S200 series miniature circuit breakers. Product documentation lists compatibility with several members of the S200 family, including S200, S200M, S200P and S200S variants. The accessory system allows additional functions to be integrated into the modular circuit protection arrangement.

Compatibility should always be confirmed against the exact circuit breaker type before installation. ABB S200 accessories are available in several configurations, including left-mounted and right-mounted auxiliary contacts, signal contacts, shunt releases, undervoltage releases, and other functional modules. The physical mounting position and accessory type therefore form an important part of product identification.

Left-Side Mounting Design

A defining feature of the S2C-H11L is its left-side mounting arrangement. The accessory is designed to attach to the side of the compatible miniature circuit breaker, creating an integrated assembly while maintaining the modular design of the S200 system.

The side-mounted arrangement is useful in distribution and control panels where circuit protection devices are installed on DIN rails. By positioning the auxiliary contact directly beside the circuit breaker, the additional status-monitoring function can be incorporated without requiring a separate standalone switching device.

The compact modular arrangement also supports organized panel construction. When multiple circuit breakers and accessories are installed together, the correct accessory configuration and mounting sequence should be followed according to the applicable ABB installation documentation.

Electrical Status Monitoring

The primary function of the ABB 2CDS200936R0001 is to provide an indication of the position of the associated switching device. This makes the accessory suitable for applications where the state of a miniature circuit breaker must be detected remotely.

For example, an auxiliary contact can be connected to an indicator or control input so that a control panel can determine the status of a protected circuit. In automation installations, the contact state may also be incorporated into a PLC input circuit or relay-based control logic. The actual circuit arrangement depends on the electrical design and the requirements of the installation.

Technical Characteristics

The S2C-H11L has a compact construction intended for modular low-voltage electrical equipment. ABB product information lists a net width of approximately 8.8 mm, a height of approximately 85 mm, and a depth of approximately 69 mm. The product weight is approximately 0.04 kg.

The documented power loss is up to 1 W. The device is categorized as an auxiliary contact accessory rather than a primary miniature circuit breaker. Its purpose is therefore to provide supplementary switching information associated with the operating state of the connected protection device.

Typical Applications

The ABB 2CDS200936R0001 can be used in electrical distribution and control applications where the status of an S200 miniature circuit breaker needs to be monitored. Typical system environments include distribution boards, control panels, automation cabinets, machine control systems, building electrical installations, and industrial low-voltage equipment.

In a distribution panel, the auxiliary contact can provide an electrical status signal to an indication circuit. In an automation cabinet, the contact may be incorporated into a control sequence or monitoring circuit. In machine installations, breaker status information can be used as part of an interlocking or supervisory function, depending on the system design.

Installation Considerations

Before installation, the exact miniature circuit breaker model should be checked against the compatibility requirements for the S2C-H11L. The accessory is intended for compatible ABB S200 family devices, and the correct mounting position should be confirmed before assembly.

The auxiliary contact should be installed according to the applicable ABB instructions. Electrical connections should be made according to the circuit design and the relevant electrical installation requirements. The auxiliary contact should not be treated as a replacement for the main protective function of the miniature circuit breaker.

For maintenance or replacement work, the complete identification code should be checked carefully. The ABB order code 2CDS200936R0001 and type designation S2C-H11L provide the key references for identifying this particular left-mounted 1NO/1NC auxiliary contact.

Product Identification and Replacement

When selecting a replacement component, comparing only the general description “auxiliary contact” may not be sufficient. ABB offers several S2C auxiliary contact variants with different contact arrangements and mounting positions. The S2C-H11L is specifically identified by the combination of its type designation, contact configuration, and left-side mounting arrangement.

For this reason, equipment documentation, the existing accessory marking, and the associated circuit breaker type should be reviewed together. This approach helps distinguish the S2C-H11L from similar ABB accessories such as right-mounted auxiliary contacts or versions with two normally open or two normally closed contacts.

Summary

The ABB 2CDS200936R0001, identified as S2C-H11L, is a left-side auxiliary contact for compatible ABB S200 series miniature circuit breakers. It provides a 1NO/1NC contact configuration for electrical status indication and monitoring. The accessory belongs to the ABB S2C modular accessory family and is designed to integrate with compatible low-voltage circuit protection equipment.

With its compact side-mounted construction and dedicated auxiliary contact function, the S2C-H11L can be incorporated into distribution boards, control cabinets, automation systems, and other low-voltage electrical installations where circuit breaker position information is required. Correct product identification and compatibility verification are important when installing or replacing the 2CDS200936R0001.
