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.
