Square D HU36 Heavy Duty Three Phase Non-fused Disconnects 100 A NEMA 3R 600 V

HU36 Series Heavy Duty Three Phase Non-fused Disconnects

• All heavy duty safety Switches feature a quick-make, quick-break Operating Mechanism, a dual Cover Interlock and a Color-coded indicator Handle.
• An abundance of copper is used in the heaviest Current carrying Power paths of all Square D by Schneider Electric heavy duty safety Switches. The more copper for Current carrying paths, the lower the temperature rise.
• Load-make, load-break rated for the switch current rating
• Lock-Off provision is standard on all heavy duty safety switches
• According to the National Electric Code, section 690.15, PV arrays must have a disconnecting means to isolate the inverter from the PV power source.
• Utility grid-tie inverters that utilize PV arrays with voltages above 250VDC require a disconnect rated for 600VDC to perform this function
• Square D disconnects For Use With grid-tie inverters that don't already have pre-built disconnects
• It is nonfusible, rated at 600 volts DC
• The DC input of up to two sub-array can be connected to the safety switch and it is outdoor rated so it can be located close to the panels
• Can be used for disconnecting up to three PV arrays for three grid-tie inverters
• It has wiring lugs that are rated to accept two #14 to #10 wires in each lug
• The Square D F Series safety Switches provide high levels of Mechanical Endurance than NEMA KS-1 or UL98 standards require
• Red and black handle indicates the ON (red) or OFF (black) switch position
• Side-opening, left hinged covers
• The design life of a F-Series Switch is a minimum of three times the NEMA requirement
• Visible blades for positive blade position indication
