QMQB7032B - 600Amp Panelboard Switch

QMQB7032B - 600Amp Panelboard Switch

The QMQB7032B is a 600 amp panelboard switch used in higher-load electrical systems where reliability matters. It’s a 3-pole, 250 volt A.C. fusible twin unit switch that installs directly into compatible panelboards using a bolt-in connection. This mounting style helps keep the switch firmly in place and makes it a practical option when working inside existing equipment.

The switch is designed to accept Class RK1 and RK5 fuses, which are commonly used for overcurrent protection in commercial and industrial applications. Once installed, it provides straightforward on-off control while helping protect downstream circuits. The overall construction is intended for long-term use in demanding environments where equipment is expected to perform day in and day out.
