Description

Circuit breakers, or electric breakers are electrical safety devices that safeguard circuits from damage due to overcurrent, overload and short circuit. Their primary role involves interrupting current flow after the detection of faults by protective relays.

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.

The Molded Case Circuit Breakers are intended for indoor installation or for installation in covered outdoor distribution panel.

JFM1 Series MCCB ,The rated insulating voltage is 750V, suitable for AC 50/60Hz,rated working voltage 690V or below, rated working current is 12.5A to 800A of circuit and used in distributing electric energy.
