£43.74
The ABB 2CSS275101R0044, also identified as the SN201 M-C4, is a compact miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits. As part of the dependable ABB SN201M series, it combines phase and switched neutral protection within a space-saving single-module device.
This miniature circuit breaker features a C-curve tripping characteristic, making it suitable for circuits containing equipment with moderate starting currents. Its thermal and magnetic tripping mechanisms provide reliable protection by disconnecting the electrical supply when sustained overloads or short-circuit faults occur.
With a rated current of 4 A, a rated operating voltage of 230 V AC and a 10 kA short-circuit breaking capacity, the SN201 M-C4 is suitable for residential, commercial and industrial distribution systems. Its compact 1P+N configuration, with the neutral positioned on the right, allows straightforward installation inside DIN rail distribution boards and control panels.
Miniature circuit breakers such as the ABB SN201 M-C4 use thermal and electromagnetic tripping mechanisms to protect wiring and connected equipment. The thermal mechanism responds to sustained overload conditions, while the magnetic mechanism provides rapid disconnection during short circuits.
The SN201M design switches both the phase and neutral conductors while occupying only one DIN rail module. This helps reduce the space required inside distribution boards while providing clear and dependable isolation of single-phase circuits.
