UL489 Miniature Circuit Breakers

Uncompromising safety and comfort

 

UL489 miniature circuit breakers (MCBs) ensure electrical safety in multiple applications. UL489 MCBs feature two different tripping mechanisms, the delayed thermal tripping mechanism for overload protection, and the magnetic tripping mechanism for short circuit protection.

 

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

 

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
