Miniature Circuit Breakers & Supplementary Protectors

Uncompromising safety and comfort
Miniature circuit breakers (MCBs) ensure electrical safety in multiple applications. They have two different tripping mechanisms, the delayed thermal tripping mechanism for overload protection and the magnetic tripping mechanism for short circuit protection.

Benefits

Extra-wide and complete range of MCBs to cover most applications and markets
Compliance to worldwide product standards (IEC, UL, CSA)
Space and time saving thanks to the unique bottom-fixing auxiliary contact
Established and certified quality

Features

Characteristics: B, C, D, K, Z
