Why Choose the ABB S203MC10-1 Miniature Circuit Breaker?
The ABB S203MC10-1 is a high-performance three-pole miniature circuit breaker (MCB) designed to provide dependable protection against overloads and short circuits in commercial, industrial and OEM electrical installations. Part of the proven ABB System pro M compact S200M series, it combines reliable circuit protection with a compact modular design for modern electrical distribution systems.
Featuring both a delayed thermal tripping mechanism for overload protection and an electromechanical tripping mechanism for rapid short-circuit interruption, the S203MC10-1 delivers reliable protection in demanding environments. Its C tripping characteristic makes it ideal for protecting general-purpose power circuits, lighting installations and equipment with moderate inrush currents.
With a rated current of 10 A, a three-pole configuration and a 10 kA rated short-circuit capacity, the S203MC10-1 is well suited for residential, commercial and industrial distribution systems. Its DIN rail mounting and compatibility with ABB accessories simplify installation and future expansion.
