QMQB7036 - 600Amp Panelboard Switch

QMQB7036 - 600Amp Panelboard Switch

It’s a 600 amp, 3-pole, fusible twin unit rated for 600 volts AC, commonly used in commercial and industrial panelboard setups. The bolt-in design helps keep the switch firmly seated once installed, which is important in environments where vibration, heat, and daily use are factors. This model works with both Class RK1 and RK5 fuses, giving you flexibility when it comes to overcurrent protection without forcing you into a single fuse option.
