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
  • Configurations: 1P, 1P+N, 2P, 3P, 3P+N, 4P
  • Breaking capacities up to 25 kA
  • Rated currents up to 63A
  • Real contact position indication, directly connected to the moving contact
