ABB S203MT-Z16H10 miniature circuit breaker, a 3-pole 16 A Z curve MCB with 10 kA breaking capacity for sensitive circuit protection in industrial, commercial and railway electrical systems.
The ABB S203MT-Z16H10 is a dependable miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits in demanding installations. Part of the ABB S200MT miniature circuit breaker range, this 3-pole device is especially suited to industrial, commercial and railway applications where reliable circuit protection is essential.
With a 16 A rated current and Z-type tripping characteristic, the S203MT-Z16H10 provides sensitive magnetic tripping for circuits requiring fast fault disconnection. This makes it suitable for control circuits, signalling systems and applications where sensitive short-circuit protection is required.
The ABB S203MT-Z16H10 features a compact DIN rail mounting format and current-limiting construction, helping reduce fault energy and protect downstream equipment. Its modular 3-pole design supports straightforward installation inside control panels, distribution boards and electrical cabinets.
Miniature circuit breakers such as the ABB S203MT-Z16H10 automatically disconnect electrical circuits when overload or short-circuit conditions occur. This helps protect cables, connected equipment and downstream components from excessive current and fault energy.
The Z curve characteristic provides fast magnetic tripping sensitivity, making this MCB suitable for circuits that require rapid disconnection under fault conditions. Its 3-pole configuration enables simultaneous protection and isolation of three-phase circuits in professional electrical systems.
