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
UL1077 MCBs feature two tripping mechanisms, the delayed thermal tripping mechanism and the magnetic tripping mechanism, to ensure electrical safety in multiple applications.
UL489 MCBs feature two tripping mechanisms, the delayed thermal tripping mechanism and the magnetic tripping mechanism, to ensure electrical safety in multiple applications.
