Molded Case Circuit Breakers (MCCBs)

Molded case circuit breakers (MCCBs) are the circuit protection backbone of electrical power distribution systems in residential, commercial and industrial settings. They offer protection for circuits from 15 through several thousand amps and are conveniently re-settable for maximum uptime. MCCBs protect electrical systems from overloads and short circuits, ensuring safety and preventing damage to the equipment.

A NOARK’s MCCB is suitable for a variety of applications, by machinery manufacturers, control panel fabricators and power distribution OEMs. NOARK’s Molded Case Circuit Breakers are designed to withstand a wide temperature range from -40 to +70 degrees C so they can perform reliably even in demanding applications.
