Why Choose the ABB SH203M-D2 Miniature Circuit Breaker?
The ABB SH203M-D2 is a compact and reliable three-pole miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits. As part of the ABB SH200 MCB series, it combines a 2 A rated current with a Type D tripping characteristic for circuits where high starting or inrush currents may occur.
The SH203M-D2 provides thermal-magnetic circuit protection with a 10 kA rated short-circuit breaking capacity. Its Type D operating characteristic is particularly suitable for loads with substantial switch-on or magnetising currents, helping provide dependable protection without unnecessary operation during normal equipment start-up.
With its three-pole configuration, the SH203M-D2 provides coordinated protection across three conductors and is well suited to three-phase and multipole electrical applications. Its compact modular construction enables straightforward installation on DIN rail inside electrical distribution boards and industrial control panels.
