Why Choose the ABB S203C25 Miniature Circuit Breaker?
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.
