MOULDED CASE CIRCUIT BREAKERS (MCCBs)


POWERTEC MCCBs are based on the latest technologies to achieve precise circuit interuption under overload and short-citcuit fault currents. POWERTEC MCCBs comply with IEC 60947-2 and are tested at independent and approved test laboratories. We offer a wide range of MCCBs with current rating from 10A to 8000A in 2, 3 and 4 Pole versions and breaking capacity ranging from 15kA to 60kA.

Features:

  • Quick 'make and break' trip-free mechanism.
  • Clear indication of ON, OFF and TRIP position.
  • 'Push to Trip' facility for verification of proper working of operating mechanism.
  • Wide range of internal and external accessories.
  • Housing of heat resistant thermoset insulating material.
  • Suitable for wide range of ambient temp. -5 deg. C to 55 deg. C with derating as per temp compensation curve.
  • The moving and fixed contact are provide with Silver alloy tips which enhances the contact life.
  • Provide isolation function.
  • MCCB can be used for DC application.

INTERNAL ACCESSORIES

  • UNDER VOLTAGE RELEASE
    The under-voltage release act to switch off the breaker when voltage decreases to 40-35% of rated voltage. Circuit Breaker closing is possible only if the voltage exceeds 85% of the rated voltage.
  • SHUNT TRIP RELEASE
    The shunt release provides remote tripping of the breaker. Operation voltage is 70% - 110% of rated voltage.
  • TRIP ALARM CONTACT
    Alarm contact gives tripping indication once the MCCB trips. Alarm contact does not act when the relay is at normal open/close status. Only after free release alarm (or fault release) can the contact change its original position.
  • AUXILIARY CONTACT
    The auxiliary contact is used for remote signaling and control operation. It indicates the breaker status whether open or closed.
