Molded case circuit breakers (MCCBs) protect higher-current circuits, typically 15 to 2,500 amps, in panelboards, switchboards and equipment.

MCCB Features

Thermal-magnetic trip units – standard protection
Electronic trip units – adjustable settings
High interrupting ratings – high fault currents
Accessories – shunt trips, auxiliaries and handles

Choosing an MCCB

Select frame size, current rating, interrupting rating and trip unit. Confirm lug sizes and mounting.

Centro supplies molded case circuit breakers.
