ABB Miniature Circuit Breaker 1-Pole 20A Type B 400V AC 6 kA Breaking Capacity SN201

ABB SN201 Miniature Circuit Breaker model SN201 is a new, high-quality electrical protection device designed for industrial, commercial, and residential use. With a single pole configuration, this MCB provides reliable circuit protection for a 20 amp current rating at a 400V AC supply voltage. It delivers a breaking capacity of 6 kiloamperes, ensuring safety during fault conditions and short circuits.

The device features Type B tripping characteristics, allowing rapid disconnection in case of overloads or short circuits commonly found in residential settings and inductive load circuits such as motors and transformers. The toggle switch actuator provides a clear visual indication of the breaker's status and enables quick manual reset after a trip event.

The SN201 series MCB is mounted on a standard DIN rail, facilitating integration into electrical panels with compact dimensions of 18mm width, 85mm height, and 69mm depth. Its screw terminal contact type ensures firm and secure electrical connections even in demanding operating conditions.

ABB has engineered this MCB to comply with IEC/EN 60898-1 standards, guaranteeing international safety and performance benchmarks. The product's IP20 rating offers protection against solid foreign objects and restricts finger access, adding a layer of security in varied installation environments.
