Square D Safety Disconnect Model: HU361RBD. Square D makes great disconnects to protect your solar PV power system. Ideal for remote home power where Solar PV panels are used.
Amps: 30 Amps
Poles: 2 or 3 for PV
NEC National Electric Code, section 690.15, requires Solar PV Panel arrays to have disconnecting means to isolate the inverter from the PV power source.
NEC requires utility grid-tie inverters which utilize Solar PV panel arrays with voltages above 250 VDC, require a 600 VDC rated disconnect to perform this function.
For off grid inverters that do not include a DC disconnect, one of these can be used. The Square-D 600 VDC 30 Amp 3-pole safety switches are rated by the factory to handle one 600 VDC circuit per pole. Protect your solar PV power system.
Square D includes 30 A switch is rated for 15 A Isc for non-fused and 12.8 A Isc for fused. The 60 A switch is rated for 48 A Isc for non-fused and 38 A Isc for fused. Square D 100 A switch is rated for 80 A Isc for non-fused and 64 A Isc for fused. Square-D used for disconnecting up to 3 PV arrays for 3 grid-tie inverters. All Square-D 600 VDC disconnects are rated for disconnecting one circuit at full rated power using 2 poles in series.
Usually 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 30 Aamp /240 V disconnect works for up to 5 kW at 240 VAC. 60 A disconnect works for up to 11 kW. Use an AC load center to connect multiple inverters to a single disconnect. Designed for protecting your solar PV array and you.
Square D safety disconnect allows you to isolate your Solar PV array from your system.
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.
Be sure to use Class R fuses of the 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.
