£15.25
Why Choose the ABB S2C-H01 Bottom-Fitting Auxiliary Contact?
The ABB S2C-H01 is a compact bottom-fitting integrated auxiliary contact designed for compatible ABB modular circuit protection devices. It provides 1 normally closed (1 NC) contact for remote indication of the open or closed state of the associated protective device.
Designed to fit beneath compatible devices rather than occupying additional side space, the S2C-H01 is particularly useful in densely populated DIN-rail assemblies. It supports ABB S200 series and S300P MCBs, as well as compatible DS201 and DSE201M RCBOs, DS-ARC1 AFDDs and SD200 switch-disconnectors.
The S2C-H01 has a conventional free-air thermal current of 7.5 A and supports utilisation ratings including AC-14 2 A at 230 V. Its integrated design, compact dimensions and dedicated status-signalling function make it a practical accessory for professional distribution, monitoring and control applications.
Key Advantages
- Provides 1 normally closed auxiliary contact.
- Bottom-fitting design minimises additional DIN-rail width.
- Provides remote indication of the associated device's open or closed state.
- Compatible with multiple ABB MCB, RCBO, AFDD and switch-disconnector families.
- Compact 19 × 17 × 17.5 mm construction.
- Suitable for signalling, monitoring and control circuits.
Key Features
- ABB S2C-H01 integrated auxiliary contact.
- 1 NC contact configuration.
- Bottom-fitting installation arrangement.
- 7.5 A conventional free-air thermal current.
- AC-14: 2 A at 230 V.
- DC-12 / DC-13: 1 A at 50 V or 2 A at 30 V.
- Minimum operational current of 10 mA at 12 V AC/DC.
- Accepts conductors from 0.75–2.5 mm².
- 0.5 Nm terminal tightening torque.
- Mechanical service life of approximately 4,000 operations.
Space-Efficient Remote Status Indication
Auxiliary contacts electrically report the open or closed state of the protective device to which they are mechanically coupled. This enables circuit-breaker status to be incorporated into indication lamps, PLC inputs, building-management systems and other monitoring or control circuits without directly carrying the protected circuit load.
The ABB S2C-H01 achieves this functionality in a bottom-fitting format, helping preserve lateral DIN-rail space. Its 1 NC contact, broad compatibility with ABB modular protection products and compact construction make it particularly useful where panel space and reliable remote status indication are both important.
Typical Applications
- Remote circuit-breaker position indication.
- Electrical distribution boards.
- Commercial and industrial switchboards.
- Building management and monitoring systems.
- PLC and control-system status inputs.
- Compact DIN-rail assemblies where side space is limited.
