Moulded Case Circuit Breaker

Moulded case  circuit  breaker  widely  known as  MCCB  used for the  protection  of  electrical  machineries. However, it might cause a fire hazard if it is not  trip on  time or  if the  contact resistance is relatively higher. So, a regular maintenance should be done on MCCB for proper and safe operation of the MCCB. We, Edge Engineering use primary current injector, micro-ohm meter and insulation tester to test the MCCB. The testing parameters that we measure at the time of annual inspection are as below.

Maintenance of a MCCB according to NFPA 70B

  1. Contact Resistance
  2. Insulation Test
  3. Tripping Testing
