Description
Molded Case Circuit Breakers (MCCB) is an electrical protection device to protect electrical circuits from damage by overcurrent. Prevents overload, short circuit and switching of circuits.
Molded Case Circuit Breakers are designed for higher current ratings and can provide overcurrent and short circuit protection.They are used to protect low-voltage electrical circuits and equipment .They are named “molded case” because their outer housing is typically made from a molded insulating material.
JFM4 Molded Case Circuit Breaker MCCB with fixed settings, rated form 15 to 630 A.For simple applications in Middle or small buildings.
