Why Choose the ABB S204M-K63 Miniature Circuit Breaker?
The ABB S204M-K63 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 current-limiting protection with a K tripping characteristic for residential, commercial and industrial electrical distribution applications.
The S200M series uses a delayed thermal tripping mechanism for overload protection and an electromechanical tripping mechanism for short-circuit protection. Its modular design supports straightforward installation and integration within distribution boards and control panels, while compatible accessories can extend the functionality of the breaker.
With a 63 A rated current, four-pole configuration and 10 kA rated breaking capacity, the S204M-K63 is suitable for protecting circuits supplied by AC electrical systems. Its DIN-rail mounting and compact modular format make it practical for modern low-voltage distribution equipment.

Reliable Circuit Protection for Electrical Installations
Miniature circuit breakers such as the ABB S204M-K63 protect electrical circuits by responding to excessive current conditions. The thermal release provides delayed protection against overloads, while the electromechanical release responds to short-circuit conditions, helping protect conductors and connected equipment.
The S200M series is designed for flexible low-voltage distribution applications and is available in multiple pole configurations, current ratings and tripping characteristics. The K characteristic is intended for applications where equipment can produce higher starting or inrush currents, while the four-pole configuration provides protection across the specified circuit poles.
Typical Applications
- Commercial electrical distribution boards.
- Industrial control panels and distribution systems.
- Residential and building electrical installations.
- Machinery and industrial equipment circuits.
- Motor and transformer circuits requiring a K tripping characteristic.
- Low-voltage AC circuit protection and branch circuits.
