All heavy duty safety switches feature a quick-make, quick-break operating mechanism, a dual cover interlock, and a color coded indicator handle. This three blade non-fusible heavy duty safety switch that is rated at 30A with a voltage 600 VAC and 600 VDC. This short circuit rating for a non-fusible switches is based upon the Square D circuit breakers or Mag-Gard motor circuit protectors chosen as upstream protection This switch is Type 12 rated with a galvannealed steel enclosure and comes with factory installed viewing window and are surface mounted. The safety switch has a 3-wire configuration of 3 poles but a solid neutral can be installed in the field using solid neutral kit. The disconnect comes with factory installed equipment ground lugs. The wire range for this switch is AWG 12...AWG 6 aluminium and AWG 14...AWG 6 copper. All heavy duty safety switches are tested per UL98 and NEMA KS1 standards and listed in the UL files E2875 and E154828.
