- DIN-rail mounting fits standard control-panel layouts
- Non-fusible design eliminates fuse replacement and inventory
Three-Phase Enclosed Switch
The SQUARE D V1 is a non-fusible load break switch rated 20 A for three-phase circuits. It mounts on a DIN rail inside a non-metallic IP20 enclosure measuring 3 in high and 2 1/4 in deep. The unit provides a 6 mm shaft opening for external operation and carries a standard duty rating for industrial machinery applications.
Replaces Fusible Disconnects
This switch suits installations that need visible isolation without over-current protection in the same housing. The jump is worth it when local codes allow separate fusing and the panel builder wants a compact 3-pole device rated 5 hp at 240 V AC and 10 hp at both 480 V AC and 600 V AC. It does not serve buyers who need integrated fuse holders or a neutral assembly in the same enclosure.
Verify Shaft Access And Mounting
Confirm the panel cut-out accepts the 0.24 in shaft and that DIN rail space matches the enclosure depth. Check that the three-wire, three-pole configuration matches the motor circuit and that IP20 protection meets the environmental requirements of the installation. Ensure the non-metallic housing is compatible with the intended mounting surface and ambient conditions.

Questions about this item
What DIN rail size does the 3 in high by 2 1/4 in deep enclosure mount on?
The enclosure uses a DIN rail mounting style; the 3 in height and 2 1/4 in depth match standard rail profiles used in control panels.
How do you connect the three phase conductors to the 20 A non-fusible switch?
Wire each of the three conductors to the corresponding pole terminals; the non-fusible design means no fuse holders are present, so the step often missed is verifying that all three wires are fully seated before energising.
When should the IP20 non-metallic housing be inspected or replaced?
Inspect the housing for cracks, discolouration or contamination during routine panel maintenance; replace it if the IP20 protection is compromised or after any fault current event.
