ABB S400M Series Miniature Circuit Breaker, 8A Current, 230V Rated AC Voltage - 2CCS571103R8085

This miniature circuit breaker provides thermal and electromechanical protection for low-voltage single-phase installations. Designed to interrupt overcurrents and short circuits, it operates within domestic and light-commercial distribution panels and integrates a manual reset I/O actuator for straightforward switching. The unit conforms to industry protection standards and fits standard DIN-rail assemblies.

Features and Benefits:

• 10kA breaking capacity provides short-circuit interruption performance
• Type B tripping characteristic protects against low-level inrush currents
• 2-pole configuration isolates both conductors for safer maintenance
• Screw Terminal ensures secure conductor clamping and straightforward wiring
• Electromechanical thermal tripping offers combined instantaneous and overload protection

Applications

• Suitable for single-phase consumer units in homes
• Ideal for protecting lighting circuits and small appliances
• Used with distribution boards in light-commercial premises
• Can be used for branch-circuit protection with residual-current devices

What protection behaviour does it provide against sustained overloads?

The thermal element responds to prolonged overcurrent by opening the circuit when temperature rise indicates overload.

How does the device handle short-circuit events?

The electromechanical mechanism delivers Rapid magnetic tripping to interrupt high fault currents up to its 10kA capacity.

What level of enclosure protection does it offer against contact?

The housing conforms to IP20, preventing access to live parts with normal tools or fingers.

How is the unit operated for resetting after a trip?

A front-mounted I/O actuator permits manual reset and clear Visual indication of contact position.

What standards support its suitability for domestic installations?

It is manufactured to meet IEC/EN 60898-1 requirements relevant to household and similar electrical circuits.
