Moulded case circuit breakers (MCCB) prove to be effective alternative for replacement of fuses

2007-05-03 - Providing a reliable and economic protection fuselists are traditionally used on the LV switchboard as feeders. Modern fuselists can be equipped with remote monitoring equipment, but the replacement of the fuse is a manual operation requiring service personnel.

Moulded Case Circuit Breakers, MCCB's, are increasingly used as alternative. Offering state-of-the-art relay functions, this resettable protection device can be custom tailored to most applications and remotely monitored.


Adding a motorized unit, the MCCB can be made remote controlled. Modern MCCB's are offering this motorized unit as standard extras, and when equipped with this operation could be done from control centrals, or even automatically through the local intelligence system.

Moulded case circuit breakers are also used as incoming breakers on low voltage switchboards, where motorized units can also apply.
