£157.09
The ABB S203M-Z32 is a premium three-pole miniature circuit breaker (MCB) designed to provide dependable overload and short-circuit protection for industrial, commercial and panel building applications. As part of the proven ABB S200M System pro M compact series, it delivers reliable protection, compact installation and long service life in demanding electrical environments.
Featuring a Z tripping characteristic, this MCB is specifically designed for protecting highly sensitive electrical and electronic equipment where rapid magnetic tripping is required. It is ideal for PLC systems, instrumentation, electronic control circuits and other applications with low inrush currents. Its current limiting design helps reduce fault energy and minimise damage to connected equipment.
With a 32 A rated current, three protected poles and a 10 kA rated short-circuit breaking capacity, the ABB S203M-Z32 provides reliable protection for three-phase distribution systems, machinery control panels and industrial automation installations.
The ABB S203M-Z32 automatically disconnects electrical circuits during overload and short-circuit conditions, helping protect wiring, control equipment and connected devices from damage. Its advanced thermal and magnetic tripping mechanisms deliver dependable protection while maintaining excellent operational reliability.
The Z characteristic is intended for highly sensitive electronic circuits where fast magnetic tripping is required. This makes the S203M-Z32 particularly suitable for automation equipment, PLCs, instrumentation and precision control systems.
