Why Choose the ABB SH204-B40 Miniature Circuit Breaker?
The ABB SH204-B40 is a reliable four-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits. As part of the ABB SH200 MCB series, it provides dependable circuit protection for residential and commercial electrical installations.
Featuring a 40 A rated current, Type B tripping characteristic and 6 kA rated short-circuit capacity, the SH204-B40 is suitable for circuits with relatively low inrush currents. Its four-pole configuration enables simultaneous protection and isolation across four conductors, making it particularly useful in three-phase distribution systems where four-pole switching is required.
The SH204-B40 is designed for DIN-rail installation and complies with IEC/EN 60898-1. Its compact four-module construction, clear ON/OFF position indication and screw-terminal connections make it a practical protection device for distribution boards and consumer electrical installations.
