ABB S203C25 3-pole 25 A miniature circuit breaker with C curve tripping characteristic and 6 kA breaking capacity for overload and short-circuit protection.
£77.44
The ABB S203C25 is a high-quality 3-pole miniature circuit breaker (MCB) designed to provide dependable protection against overloads and short circuits in residential, commercial and industrial electrical installations. As part of the proven ABB System pro M Compact S200 series, it combines reliable thermal-magnetic protection with robust construction and long-term operational performance.
Featuring a C curve tripping characteristic, the S203C25 is ideal for circuits with moderate inrush currents, making it suitable for motors, pumps, compressors, HVAC equipment and general-purpose industrial power distribution. The breaker incorporates current-limiting technology to minimise fault energy and improve system safety.
With a rated current of 25 A, a 3-pole configuration and a 6 kA short-circuit breaking capacity, the ABB S203C25 is designed for three-phase systems operating at up to 400 V AC. Its compact DIN rail mounting design allows quick installation into distribution boards, switchgear assemblies and industrial control panels.
The ABB S203C25 automatically disconnects electrical circuits whenever overload or short-circuit conditions occur, helping to protect wiring, switchgear and connected equipment from electrical faults. Its thermal-magnetic operating mechanism delivers dependable long-term protection whilst reducing downtime.
The C curve characteristic makes the breaker particularly suitable for circuits supplying motors, pumps, compressors, HVAC systems and other inductive loads with moderate starting currents. The current-limiting design further reduces stress on electrical installations during fault conditions.
