Why Choose the ABB S203MT-K1.6 Miniature Circuit Breaker?
The ABB S203MT-K1.6 is a robust and compact 3-pole miniature circuit breaker (MCB) developed for dependable overload and short-circuit protection in traction, railway and industrial control applications. As part of the specialist ABB S200MT miniature circuit breaker range, it is engineered to deliver reliable circuit protection in demanding environments where safety, durability and operational continuity are essential.
This miniature circuit breaker combines a delayed thermal tripping mechanism for overload protection with an electromechanical tripping mechanism for short-circuit protection. Its K characteristic is ideal for circuits with moderate inrush currents, helping minimise nuisance tripping while providing effective protection for connected equipment and electrical installations.
With a rated current of 1.6 A, a 3-pole configuration and a rated short-circuit capacity of 10 kA, the S203MT-K1.6 is well suited to low-current three-phase control circuits, signalling systems and auxiliary electrical equipment. Its DIN rail mounting format allows quick installation inside electrical control panels and distribution boards.
