ABB Miniature Circuit Breaker Series Contact Block, 230V, 1 NC

This contact Block is a Compact electrical switching component designed to provide a normally closed auxiliary contact for miniature circuit breaker installations. It is intended for use in industrial control and automation panels where a low-current, reliable changeover Interface is required and operates within a defined temperature range.

• 1NC configuration provides a dedicated normally closed contact for control circuits
• Rated for 6A current to handle small control and signalling loads
• 230V voltage rating permits use in common low‑voltage control systems
• Screw Terminal connection allows secure, maintenance‑friendly wiring
• Meets multiple safety approvals to suit varied regulatory environments
• Operates from -25°C to 70°C to tolerate broad ambient conditions

• Suitable for auxiliary signalling circuits in distribution boards
• Ideal for integration into automation control panels
• Used with electrical protection devices as an auxiliary contact
• Can be used for status feedback in industrial switchgear
• Used for low-current interlock functions in machinery control

It uses screw terminals to secure conductors, enabling straightforward field wiring and reliable mechanical contact.

The unit carries multiple approvals including CE, UL and cULus, and complies with RoHS and CCC standards for use where those certifications are required.

The component is specified to function at temperatures down to -25°C and up to 70°C, covering typical indoor and controlled industrial environments.

Its physical footprint is very small, measuring 0.028 m in length by 0.044 m in height by 0.01 m in width, which supports dense mounting in confined enclosures.
