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.

Wholesale Solar recommends this Square D HU361RB disconnect for use with gridtie inverters that don't already have pre-built disconnects. It is non-fusible, rated at 600 volts DC, and 30 amps. It is outdoor rated so it can be located close to the panels or outside of your house and garage. It has wiring lugs that are rated to accept #14 to #6 wires in each lug.

About Square D

Square D—A Schneider Electric Brand

One of the most trusted names in electrical distribution, power and control—from residential to industrial construction.


In 2003, the Square D by Schneider Electric brand celebrated its 100th anniversary. One hundred years of know-how and innovation in electricity and automation management.

1902: Founding of Detroit Fuse and Manufacturing which produced fuses in cases and fuse switches in boxes.

The reputation of the "D" logo emblazoned on the company's conduit boxes led the company to choose the name Square D. In the 1940s, Square D counted 10 factories in the United States and a workforce of 7,000, manufacturing half of all the circuit breakers used in aviation.

In the 1950s, the company opened its first European subsidiary. Subsidiaries were also opened in Asia and South Africa. The brand launched programmable robots, a new generation of boxes for residential use, a fire detector for protection against current overcharge and the detection/interruption of electric arcs.

In 1991, Schneider Electric acquired Square D.

Products and systems developed by the Square D by Schneider Electric brand are present in all sectors of activity, from circuit breakers to monitoring and control systems. The tertiary and residential building sectors are major consumers of Square D by Schneider Electric products.
