Why Choose the ABB S203MC2-1 Miniature Circuit Breaker?
The ABB S203MC2-1, also identified as S203M-C2, is a premium three-pole miniature circuit breaker (MCB) engineered to protect electrical circuits against overloads and short circuits. As part of the proven ABB System pro M compact S200M series, it delivers dependable protection for residential, commercial and industrial electrical installations.
The circuit breaker incorporates both a delayed thermal tripping mechanism for overload protection and an electromechanical tripping mechanism for rapid short-circuit interruption. Its C-curve tripping characteristic makes it suitable for general power distribution circuits, lighting systems, control panels and equipment with moderate inrush currents.
With a rated current of 2 A, a three-pole configuration and a 10 kA rated short-circuit capacity at 230/400 V AC, the S203MC2-1 provides reliable protection for low-current three-phase circuits. Its compact modular construction enables straightforward installation on standard 35 mm DIN rails inside electrical distribution boards and industrial control panels.
