      General

      AC 1P 63A MCB TOMC3-63’s product performance is good, and the contact resistance is far below the standard requirements. It can deal with various types of failures, provide comprehensive protection for lines and equipment, avoid unnecessary power outages, and improve transmission reliability and safety.

      1. MCB is for non-professional operation by those untrained, and no maintenance is required
      2. Satisfying conditions and applications as mentioned above,MCB with “ON-OFF” indicating device is considered suitable for isolation function.
      3. Particular devices such as surge protective devices,surge arrester etc are recommended to install at upstream line to MCB as precaution against potential surge voltage and current occurring at its power input side.
      4. Appropriate tripping curve being chosen and properly installed, MCB trips and switches off its protected circuit in case of fault, and thus provides protection against electric shock.
      5. B,C,D tripping curve(see graphics 1):
