- DIN-rail mount enables quick panel installation
Three-Phase Load Break Switch
The SQUARE D V2 Load Break Switch is a non-fusible, three-pole, single-throw device rated at 40 amps for three-phase circuits. It provides manual isolation for motor loads up to 5 horsepower at 240 volts AC, 10 horsepower at 480 volts AC and 15 horsepower at 600 volts AC. The enclosed, non-metallic housing carries an IP20 rating and is designed for standard duty applications.
DIN Rail Mounted Non-Metallic Enclosure
The unit mounts on a DIN rail and features a non-metallic housing measuring 3 inches in height and 2 1/4 inches in depth. An opening for a 0.24 inch (6 mm) shaft allows external handle operation while the enclosure remains closed. With no neutral assembly included and a three-wire, three-pole configuration, wiring is straightforward for three-phase loads without a neutral conductor.
Non-Fusible Motor Disconnect Upgrade
This switch replaces a basic fusible disconnect or simple toggle when a visible, load-break rated means of isolation is required for three-phase motors. The jump is worth it when the application demands a compact, enclosed disconnect that breaks load current directly without relying on fuse operation for switching. It is not suited for circuits requiring integrated overcurrent protection or a switched neutral pole.
Highlights
- 3-pole switching isolates three phases simultaneously

Questions about this item
What does the 40 A current rating mean for my three-phase circuit?
The 40 A rating is the maximum continuous current each of the three poles can carry on a standard-duty three-phase circuit.
Will this 2 1/4 in deep, 3 in high non-metallic enclosure fit on my DIN rail?
Yes, the enclosed housing is designed for DIN-rail mounting and measures 2 1/4 in deep by 3 in high.
How do I connect the 0.24 in shaft opening, and what mistake should I avoid?
Insert a 6 mm (0.24 in) operating shaft into the front opening; the common error is using a shaft with the wrong diameter, which prevents proper engagement.
