Model:  HU364RB



Square D Safety Disconnect Model: HU364RB. Square-D safety disconnect isolates your Solar PV array from your solar home power system. Required by NEC code for larger solar arrays this Square D safety disconnect is fused are ready for 200 amp loads.

AC/DC: Yes

Fused: Yes

Amps: 200 Amps

Poles: 2 or 3 for PV

Regulatory affairs National Electric Code NEC, section 690.15, requires solar PV module arrays to have a disconnecting means to isolate the inverter from the PV panel power source.

Net metering grid-tie inverters that use PV Panel arrays with voltages above 250 VDC require a 600 VDC rated disconnect. For grid tie inverters that do not include a DC disconnect, this Square D safety disconnect can be used. The Square-D safety disconnect at 100 Amps has 3-pole safety switches rated by Square-D to handle one 600 VDC circuit per pole. Isolate your Solar PV panel.

Square D safety disconnect has a 100 Amp switch rated for 80 A for non-fused and 64 A for fused panels. Square D safety disconnect can also be used for disconnecting up to 3 PV arrays for 3 grid-tie inverters.

All Square-D safety disconnect panels have 600 VDC disconnects are rated for disconnecting one circuit at full rated power using 2 poles in series.

Often grid tie utilities require an AC disconnect between a grid-tie inverter and the AC load center, close to the AC service entrance, and with a visible and lockable handle. A 30 A /240 V disconnect works for up to 5 kW at 240 VAC and the 60 A disconnect works for up to 11 kW. Use an AC load center to connect multiple inverters to a single disconnect.

Square-D breakers can be back-fed with the inverter outputs and the load center main lugs will handle the combined outputs to be connected to the AC disconnect.

Please usse Class R fuses of proper voltage and amperage for fused disconnects. Square D 600 VDC fuses will not fit into 240 VDC disconnects, and 250 VAC/125 VDC fuses will not fit into 600 VDC disconnects.
