Why Choose the ABB S204M-Z63 Miniature Circuit Breaker?
The ABB S204M-Z63 is a four-pole miniature circuit breaker (MCB) designed to protect electrical installations against overloads and short circuits. As part of the ABB System pro M compact S200M series, it combines reliable circuit protection with a Z tripping characteristic for applications requiring sensitive overcurrent protection.
The S200M series uses a delayed thermal tripping mechanism for overload protection and an electromechanical tripping mechanism for short-circuit protection. Its modular construction supports straightforward installation in distribution boards and control panels, while compatible accessories can extend the functionality of the circuit breaker.
With a 63 A rated current, four-pole configuration and 10/15 kA rated breaking capacity, the S204M-Z63 is designed for AC electrical distribution applications. Its DIN-rail mounting and compact modular format make it suitable for modern low-voltage installations.
