ABB S203MT-Z10H10 miniature circuit breaker, a 3-pole 10 A Z curve MCB designed for overload and short-circuit protection in industrial, commercial and transport electrical systems.
The ABB S203MT-Z10H10 is a high-performance miniature circuit breaker (MCB) designed to provide dependable protection against overloads and short circuits in demanding electrical installations. Part of the ABB S200MT miniature circuit breaker range, this 3-pole device is suited to industrial, commercial and transport-related applications where reliable circuit protection is essential.
With a 10 A rated current and Z-type tripping characteristic, the S203MT-Z10H10 is designed for circuits requiring fast magnetic tripping sensitivity. This makes it suitable for protecting sensitive equipment, control circuits and applications where low short-circuit trip thresholds are required.
The ABB S203MT-Z10H10 features a compact DIN rail mounting format, robust current-limiting performance and a modular 3-pole configuration. Its design supports straightforward installation inside distribution boards, control panels and electrical cabinets.
Miniature circuit breakers such as the ABB S203MT-Z10H10 protect electrical circuits by automatically disconnecting the supply when an overload or short-circuit fault occurs. This helps reduce the risk of equipment damage, cable overheating and operational downtime.
The Z curve characteristic provides a sensitive magnetic trip response, making this MCB suitable for applications where fast disconnection is required. Its 3-pole design allows simultaneous protection and switching of three-phase circuits in control panels, distribution boards and specialist electrical systems.
