UL 1077 MCB

Suitable for protection against Overload & Short Circuit. 1, 2, 3, 4 Poles & 35mm DIN-rail mounting & Plug-in types Rated voltage 240/480V Characteristics: B, C, D according to IEC 60898, UL1077

  • Features
  • Ratings and Specs
Miniature Circuit Breakers are placed directly upstream of the loads and are designed to protect final loads.
They are ideal for the protection of circuits in industrial, commercial, and residential sectors, and ensures the following functions: protection against short-circuit and overload currents, isolation, protection of persons against indirect contact.
