ABB S203P-C3 3-pole 3 A C curve miniature circuit breaker with 25 kA breaking capacity for industrial, commercial and control panel circuit protection.
The ABB S203P-C3 is a high-performance 3-pole miniature circuit breaker (MCB) designed for reliable protection of low voltage electrical circuits. Part of the ABB System pro M Compact S200P range, it provides dependable overload and short circuit protection for industrial, commercial and control panel applications.
Featuring a C tripping characteristic, the S203P-C3 is suitable for general distribution circuits and loads with moderate inrush currents. Its current limiting design helps reduce fault energy during short circuit conditions, protecting cables, equipment and connected devices while improving overall installation safety.
With a rated current of 3 A, a 3-pole configuration and a 25 kA breaking capacity, this ABB miniature circuit breaker is ideal for precise protection of three-phase low current circuits. The DIN rail mounted format allows quick, secure installation in distribution boards, switchgear assemblies and industrial control panels.
The ABB S203P-C3 combines delayed thermal overload protection with electromechanical magnetic short circuit protection. This dual tripping mechanism supports dependable circuit disconnection while helping prevent damage to electrical equipment during overload or fault conditions.
The S200P range is designed for high-performance circuit protection where reliability, current limiting capability and compact installation are essential. Its compatibility with ABB System pro M Compact accessories makes it suitable for flexible panel building and professional electrical installations.
