Why Choose the ABB S2C-H20L Auxiliary Contact?
The ABB S2C-H20L is a left-side auxiliary contact designed to provide electrical indication of the contact position of compatible ABB miniature circuit breakers. Featuring 2 normally open (2NO) contacts, it allows the switching state of the associated protective device to be integrated into signalling, monitoring and control circuits.
Designed for installation on the left side of a compatible MCB, the S2C-H20L provides two independent normally open auxiliary contacts in a compact modular accessory. This makes it particularly useful where two separate indication or control functions need to respond to the operating position of the associated circuit breaker.
As part of ABB's modular circuit protection accessory range, the S2C-H20L supports professional integration of breaker-status information into distribution boards, machinery controls and building automation systems. Its dedicated mechanical interface provides a convenient alternative to external sensing arrangements while maintaining an organised panel layout.
Key Advantages
- Provides electrical indication of the associated circuit breaker's contact position.
- Features 2 normally open (2NO) auxiliary contacts.
- Designed specifically for left-side mounting.
- Allows two signalling or control functions to be operated from the breaker position.
- Suitable for integration into monitoring, automation and indication circuits.
- Compact ABB accessory for professional modular distribution assemblies.
Key Features
- ABB S2C auxiliary contact range.
- 2 normally open contacts.
- Left-side mounting configuration.
- Designed for compatible ABB modular circuit breakers.
- Provides auxiliary electrical signalling independently of the main power circuit.
- Suitable for breaker-position monitoring and control applications.
- Compact construction for DIN-rail distribution and control panels.
- ABB order code 2CDS200936R0002.
Dual Normally Open Signalling for Circuit Protection
An auxiliary contact provides a separate low-power electrical indication of a compatible circuit breaker's switching position. This information can be used by indicator lamps, relays, programmable controllers, building-management systems and other monitoring equipment without carrying the protected load through the auxiliary signalling circuit.
With two normally open contacts, the ABB S2C-H20L can provide two separate signalling paths that change state in response to the associated device. This makes the accessory useful where breaker-position information must be supplied simultaneously to more than one monitoring or control function.
Typical Applications
- MCB contact-position indication.
- Remote circuit-breaker status monitoring.
- Electrical distribution-board signalling.
- Building-management systems.
- Industrial automation and PLC input circuits.
- Machinery control panels.
- Alarm, interlocking and indication circuits.
- Compatible ABB modular circuit protection assemblies.
