Heavy-duty safety switch
The Eaton DH361UGK is a heavy-duty safety switch rated for 30 A at 600 VAC and 250 VDC. Its 3PST contact form opens three poles simultaneously for motor-circuit isolation. A steel enclosure with NEMA 1 and IP20 ratings protects the mechanism in indoor environments. The unit mounts on a flat surface for straightforward installation.
Indoor motor disconnects
This switch suits facilities that need a visible, lockable disconnect for 3-phase motors up to 30 hp at 600 VAC. Installers who require an outdoor-rated or corrosion-resistant enclosure should look elsewhere. Applications demanding integrated fuse clips or a higher ampacity than 30 A will need a different device. The IP20 rating limits use to dry, indoor locations only.
30 hp at 600 VAC rating
The 30 hp rating at 600 VAC determines the maximum motor size this switch can safely disconnect. At 480 VAC the rating falls to 20 hp, and at 240 VAC it is 10 hp. Matching the motor nameplate voltage and horsepower to these figures is the single check that confirms the part is correct.

Questions about this item
What circuit protection is required upstream for the 30 A rating?
Install a 30 A branch-circuit breaker or fuse rated for 600 VAC to protect the switch and downstream wiring.
Can the 3PST contacts switch a 240 V single-phase motor load?
Yes, the switch is rated 10 hp at 240 V AC and the three poles can interrupt a single-phase circuit.
How do I verify the switch operates correctly after mounting?
With power off, cycle the handle through ON and OFF; each pole should show continuity in ON and open circuit in OFF when tested with a multimeter.
