2CDS200946R0002 ABB S2C-H6-20R Auxiliary Contact 2NO

Why Choose the ABB S2C-H6-20R Auxiliary Contact?

The ABB S2C-H6-20R is a compact auxiliary contact with two normally open contacts (2NO), designed to provide electrical status indication from compatible ABB modular protection devices. Identified by ABB order code 2CDS200946R0002, it forms part of ABB's MCB accessories portfolio and provides a practical solution for adding signalling functionality to professional modular circuit protection installations.

Designed for right-side mounting on compatible ABB devices, the S2C-H6-20R mechanically follows the switching position of the associated protection device and transfers that status to external signalling, monitoring or control circuitry. This allows circuit-breaker position information to be integrated into distribution-board indication, building-management systems and industrial automation without using the main power circuit for signalling.

The S2C-H6-20R features a 2NO contact configuration, providing two independent normally open signalling paths. Its compact modular construction makes it particularly suitable for DIN-rail assemblies where reliable auxiliary status feedback is required while maintaining an organised and space-efficient panel layout.

Reliable Auxiliary Status Signalling

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

The ABB S2C-H6-20R provides two normally open contacts in a right-mounted configuration. Its 2NO arrangement is particularly useful where two independent normally open signalling paths are required from a compatible ABB modular protection device, supporting flexible integration into professional monitoring, automation 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.
