Why Choose the ABB S204D32 Miniature Circuit Breaker?
The ABB S204D32, also identified as S204-D32, 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 delivers reliable protection for commercial, industrial and specialist electrical installations.
The circuit breaker combines a delayed thermal tripping mechanism for overload protection with an electromechanical tripping mechanism for rapid short-circuit interruption. Its D-curve tripping characteristic makes it ideal for circuits with high inrush currents, including motors, transformers, compressors, welding equipment and industrial machinery.
With a rated current of 32 A, a four-pole configuration and a rated short-circuit capacity of 6 kA at 230/400 V AC, the S204D32 provides dependable protection for three-phase installations requiring neutral switching. Its compact modular design enables straightforward installation on a standard 35 mm DIN rail inside distribution boards, switchboards and industrial control panels.
