1SYS274012R0061

The ABB SB204M-D6 miniature circuit breaker (MCB), with order code 1SYS274012R0061, belongs to ABB's System pro M compact SB200M series. It is a current-limiting protective device designed to protect electrical circuits against overloads and short circuits.The circuit breaker incorporates a delayed thermal tripping mechanism for overload protection and an electromagnetic tripping mechanism for short-circuit protection. It features a rated current of 6 A, a D-type tripping characteristic, four poles and a rated short-circuit breaking capacity of 10 kA at the applicable rated voltage.

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