Industrial Photocontrol Switch

The NSI TORK 2000-2 is a raintight photocontrol switch rated for 4620 W at 208 to 277 V AC. It mounts through a 1/2 in conduit opening and uses an SPST contact form. The polycarbonate housing includes a gasket and lock nut for outdoor installation.

Suits Dusk-to-Dawn Lighting Loads

Designed for compact fluorescent, HID, inductive and LED fixtures up to 4620 W or 16.7 A incandescent and 10 A ballast. Not for circuits that exceed the 277 V limit, for loads above the stated wattage or amperage, or for applications requiring adjustable timing beyond the fixed dusk-to-dawn operation.

Verify Voltage and Conduit Compatibility

Confirm the supply voltage falls within the 208 to 277 V AC range. Ensure the mounting location accepts a 1/2 in conduit entry and that ambient temperatures stay between -40 and 140 degrees F. Check that the connected load type and current draw remain within the published maximums.

Questions about this item

What voltage supply do I need for the 208-277 V photocontrol?

The unit operates on 208 to 277 V AC, so your circuit must provide voltage within that range.

Will the 10 A ballast rating handle my existing HID fixtures?

The switch supports up to 10 A for ballast loads; verify each fixture's amp draw stays at or below that limit.

How can I confirm the dusk-to-dawn cycle is active after wiring?

Cover the sensor to simulate darkness; the load should turn on at 1.0 to 5.0 foot-candles and off again at 3 to 15 foot-candles.
