Circuit Breakers
Miniature circuit breakers are applied to protect electric applications against an over current. When an electrical circuit is not protected the application can be damaged and unsafe situations may happen like fire. Mors Smitt delivers a wide range of miniature circuit breakers specially designed and tested according to railway regulations.
