ABB S203MT-K16H10 miniature circuit breaker, a 3-pole 16 A K curve MCB with 10 kA breaking capacity for industrial, commercial and transport electrical protection.
The ABB S203MT-K16H10 is a reliable miniature circuit breaker (MCB) designed to provide dependable protection against overloads and short circuits in demanding electrical installations. As part of the ABB S200MT miniature circuit breaker range, this 3-pole device is suitable for industrial, commercial and transport-related applications where robust circuit protection is required.
With a 16 A rated current and K-type tripping characteristic, the S203MT-K16H10 is designed for circuits with higher inrush currents, such as motors, transformers and inductive loads. Its current-limiting performance helps reduce fault energy and supports safer, more reliable electrical operation.
The ABB S203MT-K16H10 features a compact modular format for DIN rail mounting, making it straightforward to install inside electrical cabinets, control panels and distribution boards. Its 3-pole design provides simultaneous protection for three-phase circuits in professional electrical systems.
Miniature circuit breakers such as the ABB S203MT-K16H10 automatically disconnect electrical circuits when overload or short-circuit faults occur. This helps protect cables, connected equipment and downstream components from damage caused by excessive current.
The K curve characteristic makes this MCB suitable for applications where higher starting currents are expected, including inductive loads, motors and transformers. Its 3-pole configuration allows three-phase circuits to be protected and isolated together within industrial control systems and distribution equipment.
