The ABB SB201-C40DC is a single-pole, 40 A miniature circuit breaker from the System pro M compact SB200 DC series. It is designed to provide protection and control for compatible direct-current (DC) electrical circuits against overloads and short circuits. The device incorporates a delayed thermal tripping mechanism for overload protection and an electromagnetic tripping mechanism for short-circuit protection. Its C-type tripping characteristic is suitable for compatible resistive and inductive loads with relatively low inrush current. With a rated operational voltage of 250 V and a rated short-circuit breaking capacity of 6 kA, this compact protective device is intended for suitable residential, commercial and industrial installations. It supports DIN-rail mounting and complies with IS/IEC 60947-2. Correct DC voltage ratings, polarity, conductor sizing and application requirements must be verified before installation.
