Why Choose the ABB 2CDS381103R0105 Miniature Circuit Breaker?
The ABB 2CDS381103R0105, designated S301P-B10NA, is a premium 1P+N miniature circuit breaker (MCB) from the ABB System pro M compact S300P range. Designed for industrial and commercial electrical installations, it provides dependable protection against overloads and short circuits whilst simultaneously switching the neutral conductor for improved circuit isolation.
Combining thermal overload protection with rapid electromagnetic short-circuit tripping, the S301P-B10NA delivers reliable circuit protection whilst incorporating ABB features such as fail-safe terminals, an integrated trip indicator, contact position indication and a dual DIN rail release mechanism to simplify installation and maintenance.
With a 10 A rated current, a Type B tripping characteristic and a 25 kA rated short-circuit breaking capacity, this circuit breaker is particularly suited to protecting lighting circuits, heating systems, instrumentation, control equipment and other circuits with low inrush currents.
