QMQB3332B w/ Mounting Kit - 30Amp Panelboard Switch

The Federal Pacific QMQB3332B is a 30-amp panelboard switch used in fusible electrical systems where reliability and straightforward installation are important. It’s a 3-pole, 3-phase switch rated for 250 volts AC and is designed to bolt directly into compatible panelboards. Because it uses a bolt-in style, the switch seats firmly in place and helps maintain solid electrical connections once installed.

This switch is intended for indoor use and is commonly found in commercial and industrial electrical rooms. It supports several common fuse classes, which makes it easier to work into existing setups without reconfiguring the entire panel. A mounting kit is included, so installers don’t have to source extra hardware before getting started.
