The ABB SB201-C50DC is a single-pole, 50 A miniature circuit breaker from the System pro M compact SB200 DC series, designed to provide protection and control for compatible direct-current (DC) electrical circuits against overloads and short circuits. It incorporates a thermal tripping mechanism for overload protection and an electromagnetic tripping mechanism for short-circuit protection. Its C-type tripping characteristic is intended for suitable resistive and inductive loads with relatively low inrush current. The device has a rated short-circuit breaking capacity of 6 kA and is intended for appropriate residential, commercial and industrial electrical installations. Its compact design supports DIN-rail mounting in compatible distribution assemblies. The circuit breaker's DC voltage rating, polarity requirements, conductor sizing and suitability for the intended application must be checked against the manufacturer's technical documentation before installation.
