National Electric Code NEC, section 690.15, requires solar PV module arrays to have a disconnecting means to isolate the inverter from the solar PV panel array. Most utility grid-tie inverters which use solar PV arrays with voltages above 250 VDC require a 600 VDC rated disconnect. Inverters that do not include a DC disconnect, this Square D safety disconnect can be used.

Square-D 600 VDC 60 Amp 3-pole safety switches are rated by the factory to handle one 600 VDC circuit per pole for Square D safety.

Square D 60 Amp switch is rated for 48 Amps for non-fused and 38 Amps for fused.

Square-D 100 A switch is rated for 80 A Isc for non-fused and 64 A Isc for fused. Square D safety disconnects are used for disconnecting up to 3 PV arrays for 3 grid-tie inverters.

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

Most 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.

Square D safety disconnect works for solar PV arrays 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. Square D safety disconnect uses the load center main lugs to handle the combined outputs to be connected to the AC disconnect.

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