Why Choose the ABB S204C50 Miniature Circuit Breaker?
The ABB S204C50, also identified as S204-C50, is a premium four-pole miniature circuit breaker (MCB) designed to provide dependable protection against overloads and short circuits. As part of the trusted ABB System pro M compact S200 series, it offers reliable protection for residential, commercial and industrial electrical installations.
The breaker combines a delayed thermal tripping mechanism for overload protection with an electromechanical tripping mechanism for rapid short-circuit interruption. Its C-curve tripping characteristic makes it suitable for general power distribution, lighting systems, HVAC equipment, control panels and machinery with moderate inrush currents.
With a rated current of 50 A, a four-pole configuration and a rated short-circuit capacity of 6 kA at 230/400 V AC, the S204C50 provides dependable protection for three-phase installations with neutral switching. Its compact modular design enables straightforward installation on a standard 35 mm DIN rail inside distribution boards, switchboards and industrial control panels.
