2CDS200936R0003 ABB S2C-H02L Auxiliary Contact 2NC Left

Why Choose the ABB S2C-H02L Auxiliary Contact?

The ABB S2C-H02L is a compact left-mounted auxiliary contact designed to provide remote electrical status indication from compatible ABB modular protection devices. Identified by ABB order code 2CDS200936R0003, it forms part of ABB's MCB accessories portfolio and provides two normally closed (2NC) contacts for signalling and monitoring applications.

Installed on the left-hand side of a compatible modular protection device, the S2C-H02L follows the switching position of the associated device and transfers this status to an external control, indication or monitoring circuit. This allows circuit-breaker position information to be incorporated into distribution-board indication, building controls and industrial automation systems without using the main power circuit for signalling.

The S2C-H02L combines its 2NC contact configuration with a slim modular design suitable for DIN-rail assemblies. Its dedicated auxiliary-contact function makes it a practical accessory for professional electrical installations requiring dependable remote indication of the operating state of compatible ABB circuit protection equipment.

Reliable Auxiliary Status Signalling

Auxiliary contacts provide a separate electrical signal corresponding to the operating position of a circuit protection or switching device. This enables device status to be communicated to indicator lamps, relays, programmable controllers, building-management systems and other compatible monitoring equipment without carrying the protected load through the signalling circuit.

The ABB S2C-H02L provides two normally closed contacts in a left-mounted configuration. Its 2NC arrangement is particularly useful where two independent normally closed signalling paths are required from a compatible ABB modular protection device, supporting flexible integration into professional monitoring and control systems.

Typical Applications

• Remote circuit-breaker position indication.
• Electrical distribution-board status monitoring.
• Building management and automation systems.
• Industrial control and signalling circuits.
• DIN-rail protection assemblies requiring auxiliary feedback.
• Alarm, interlocking and supervisory circuits using compatible ABB devices.
