QMQB6636 - 60Amp Panelboard Switch

QMQB6636 - 60Amp Panelboard Switch

The Federal Pacific QMQB6636 panelboard switch is a 60 amp, 600 volt switch used in many commercial and industrial electrical systems. It’s a 3-phase, 3-pole unit designed to handle higher power loads where consistent operation is expected. This model uses a fusible twin-unit setup, meaning overcurrent protection is handled by fuses rather than the switch alone. That’s often preferred in systems where protecting downstream equipment is important. The bolt-in mounting style allows the switch to sit firmly in place inside the panelboard, helping keep everything secure once installed.
