1SYS274012R0101

The ABB SB204M-D10 miniature circuit breaker (MCB), order code 1SYS274012R0101, belongs to ABB's System pro M compact SB200M series. It is a current-limiting electrical protection device designed to protect circuits against overloads and short circuits.

The breaker has a rated current of 10 A, four poles and a D-type tripping characteristic. Its thermal tripping mechanism provides overload protection, while its electromagnetic tripping mechanism provides short-circuit protection. The 10 kA rated short-circuit breaking capacity makes it suitable for installations where the prospective fault current is within the device's specified limits.

The D-curve characteristic is intended for circuits supplying equipment with high startup or inrush currents. Suitable applications may include commercial and industrial electrical installations, subject to correct circuit sizing and protection coordination. The SB200M product range complies with IS/IEC 60898-1.
