£78.22
The ABB S203C10 is a premium 3-pole miniature circuit breaker (MCB) designed to provide reliable protection against overloads and short circuits in commercial, industrial and residential electrical installations. As part of the trusted ABB System pro M Compact S200 series, it combines robust performance, compact dimensions and dependable operation for modern electrical distribution systems.
Featuring a C curve tripping characteristic, the S203C10 is ideal for protecting circuits with moderate inrush currents, including motors, pumps, compressors, HVAC systems and general-purpose power distribution. Its thermal-magnetic operating mechanism ensures accurate overload protection and rapid interruption during short-circuit conditions.
With a rated current of 10 A, a 3-pole configuration and a 6 kA short-circuit breaking capacity, the ABB S203C10 is suitable for three-phase electrical systems operating at 230/400 V AC. Its DIN rail mounting format allows quick installation into switchboards, distribution boards and industrial control panels.
The ABB S203C10 automatically disconnects electrical circuits when overload or short-circuit conditions occur, helping protect wiring, equipment and connected electrical loads. Its thermal-magnetic design ensures dependable operation while reducing the risk of damage caused by electrical faults.
The C curve characteristic makes the breaker suitable for circuits with moderate starting currents, making it an excellent choice for motors, control panels, HVAC equipment and general industrial distribution systems.
