£154.71
The ABB S203MT-C1.6 is a specialist 3-pole miniature circuit breaker (MCB) designed to provide reliable overload and short-circuit protection in demanding electrical installations. Part of the ABB S200MT range, it is developed for traction, railway and industrial applications where dependable modular circuit protection is essential.
With a C tripping characteristic, the S203MT-C1.6 is suitable for general-purpose circuits with moderate inrush currents. This makes it a practical choice for control circuits, auxiliary supplies, automation equipment and low-current three-phase electrical systems.
Rated at 1.6 A with a 3-pole configuration and 10 kA short-circuit breaking capacity, the ABB S203MT-C1.6 provides compact and effective protection for low-current three-phase circuits. Its DIN rail mounting format enables straightforward installation in distribution boards, control panels and industrial switchboards.
Miniature circuit breakers such as the ABB S203MT-C1.6 automatically disconnect electrical circuits when excessive current is detected. The thermal tripping mechanism provides overload protection, while the electromechanical tripping mechanism reacts quickly to short-circuit faults.
The C curve characteristic is suitable for circuits where moderate inrush currents may occur during normal operation. Combined with the specialist S200MT construction, the S203MT-C1.6 provides dependable protection for demanding transport, industrial and automation environments.
