QMQB4032R - 400Amp Panelboard Switch

The Federal Pacific QMQB4032R provides 400 amps of fused power control in commercial and industrial electrical systems. Electricians install this 3-pole, 250V AC panelboard switch as a bolt-in unit, which allows it to seat firmly in compatible panelboards without extra adjustments. Facilities use this switch to control and protect higher-load circuits where a dependable disconnect matters.
