ABB LV - Miniature circuit breakers

Miniature circuit breakers protect installations against overload and short-circuit, warranting reliability and safety for operations. System pro M compact S 200 series are current limiting overcurrent protective devices. They have two different tripping mechanisms, the delayed thermal tripping mechanism for overload protection and the magnetic tripping mechanism for short circuit protection.

Main Benefits

  • Extra-wide and complete range of MCBs to cover most applications and markets
  • Meeting worldwide standards
  • Certificates, documentation, training or background information to support customers due to their daily work
  • Space and time saving thanks to the unique bottom-fixing auxiliary contact

Main Features

  • MCB range offer the possibility to select among different characteristics (B, C, D, K, Z), configurations (1P, 1P+N, 2P, 3P, 3P+N, 4P), breaking capacities (up to 25 kA) and rated currents (up to 63A).
  • Compliance to the worldwide product standard:
    • IEC/EN 60898-1
    • IEC/EN 60947-2
    • UL 1077
    • UL 489
    • CSA 22.2 No. 235
    • CSA 22.2 No. 5 allowing the use for residential, commercial and industrial applications.
    • 35 mm² and 10 mm² cylinder lift twin terminals for challenging industrial use. Cross wiring can easily be realised by inserting the busbars into the rear terminal part and the incoming wires into the front part.
    • Real contact position indication, directly connected to the moving contact, for more comfort and safety
