ABB S203P-Z32 three-pole 32 A miniature circuit breaker with Z tripping characteristic for sensitive industrial and commercial electrical circuit protection.
The ABB S203P-Z32 is a premium three-pole miniature circuit breaker (MCB) from the renowned ABB System pro M compact S200P series. Designed to provide dependable overload and short circuit protection, it is ideal for industrial control panels, commercial distribution systems, OEM machinery and sensitive electrical installations where rapid fault protection is essential.
Featuring a Z tripping characteristic, the S203P-Z32 is specifically designed for circuits requiring very fast magnetic tripping, making it ideal for protecting sensitive electronic equipment, PLCs, instrumentation, semiconductor devices and control circuits. Its delayed thermal trip mechanism protects against overloads, while its electromechanical trip mechanism rapidly disconnects short circuit faults.
With a 32 A rated current, three-pole configuration and breaking capacities of up to 25 kA at 230 / 400 V AC, the ABB S203P-Z32 provides dependable protection for demanding commercial and industrial applications. Its compact DIN rail mounted design also enables quick installation alongside ABB modular accessories.
The ABB S203P-Z32 automatically disconnects electrical circuits during overload or short circuit conditions, helping protect cables, control equipment and connected electrical devices from damage. Its current limiting design reduces thermal and mechanical stresses during fault conditions, improving system reliability.
The Z characteristic provides an extremely fast magnetic response, making this breaker particularly suitable for protecting electronic equipment, PLC systems, semiconductor devices and other sensitive control circuits where rapid fault clearance is essential.
