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 with 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
Miniature circuit breakers (MCBs) offer many advantages to the end-user by protecting electrical installations against overloads and short circuits. They come in a wide variety of trip curves, approvals, and technical ratings. In this webinar, an ABB subject matter expert will explain how to select the right MCB for your application to increase safety and reduce downtime and cost.
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.
