£114.09
The ABB 2CDS381103R0187, also known as the S301P-K0.75NA, is a high-performance miniature circuit breaker (MCB) designed to protect industrial electrical circuits against overloads and short circuits. As part of the advanced ABB System pro M compact S300P series, it provides dependable circuit protection for control panels, machinery and demanding electrical installations.
Featuring a 0.75 A rated current, a Type K tripping characteristic and a high 25 kA short-circuit breaking capacity, this circuit breaker is particularly suitable for circuits supplying motors, transformers, solenoids and other inductive loads. Its Type K characteristic accommodates higher starting currents while maintaining effective protection against sustained overcurrent conditions.
With a 1P+N pole configuration, a rated operational voltage of 240 V AC and compatibility with selected 72 V DC circuits, the S301P-K0.75NA offers flexible protection for industrial control applications. Its compact DIN rail format, fail-safe terminals and compatibility with ABB System pro M compact accessories simplify installation within electrical panels and distribution boards.
The ABB S301P-K0.75NA automatically disconnects the protected circuit when an overload or short circuit occurs. Its thermal release responds to sustained overloads, while its electromagnetic release provides rapid interruption of high fault currents to help protect wiring and connected equipment.
The Type K tripping characteristic is designed for equipment that can produce significant inrush current during start-up. This makes the circuit breaker a suitable choice for motor circuits, transformers, electromagnetic devices and industrial control equipment where a faster tripping curve could cause unnecessary interruptions.
