S2C-H10 Auxiliary Contact

Why Choose the ABB 2CDS200970R0002 S2C-H10 Auxiliary Contact?

The ABB 2CDS200970R0002, also known as the S2C-H10, is a compact bottom-fitting auxiliary contact designed for status indication on compatible ABB modular protection devices. Part of the ABB S2C accessory range, it provides reliable indication of the position of the device contacts in low-voltage distribution boards, control panels and electrical installations.

This ABB auxiliary contact features a 1 normally open contact configuration and is used as a closing auxiliary contact for signalling the operating status of compatible devices. Its bottom-fitting design helps save DIN rail space compared with traditional side-mounted auxiliary contact accessories, making it especially useful for retrofitting into existing panels.

Suitable for ABB S200 series miniature circuit breakers, selected residual current devices and DSE200 electronic RCBOs, the S2C-H10 helps panel builders, electricians and maintenance engineers add status monitoring without unnecessary rewiring or removal of multiple devices from the rail.

Reliable Signalling for Modular Protection Devices

Auxiliary contacts such as the ABB S2C-H10 are used to provide electrical feedback from protective devices to external monitoring, signalling or automation systems. This allows the status of a circuit breaker, residual current device or related modular protection device to be monitored remotely.

The ABB 2CDS200970R0002 is particularly useful where panel space is limited. By mounting at the bottom of compatible devices, it can help reduce the need for additional rail width and simplify retrofit work in existing distribution boards and control panels.

Typical Applications

• Low-voltage distribution boards.
• Miniature circuit breaker status indication.
• Residual current device signalling circuits.
• Control panel monitoring and feedback circuits.
• Building services and electrical installation panels.
• Panel building, retrofit and maintenance applications.
