ABB S400M Series Miniature Circuit Breaker, 20A Current, 15kA Breaking Capacity - 2CCS571001R0204

This miniature circuit breaker provides overcurrent protection for low-voltage installations, combining thermal and electromechanical tripping to interrupt faults in single‑phase circuits. It is designed for panel‑mounted distribution and control systems where Compact protective devices are required and operates within both AC and DC environments.

Features and Benefits:

• 20A current rating for defined circuit protection capacity
• 15kA breaking capacity limits fault energy during short circuits
• Type C tripping characteristics for moderate inrush tolerance
• Electromechanical thermal trip breaker for combined instantaneous and overload response
• I/O reset actuator MCB screw Terminal for clear switching and secure wiring

Applications

• Suitable for residential distribution boards requiring defined protection
• Used with DC control systems at low voltages
• Can be used for single‑phase AC protection in panel assemblies

What voltages can it interrupt safely?

It is rated for use on 12V DC circuits and up to 254V AC supplies.

How many poles does the device provide?

The unit is a single‑pole device intended for individual circuit protection.

What type of terminals are used for wiring?

Connections are MADE via screw terminals to secure conductors.

How is ingress protection handled?

The enclosure meets IP20 classification for Basic touch protection and internal component safety.
