Photocontrol Swivel 480V SPST

The TORK nsi 2018 Photocontrol Swivel is a light-activated switch designed for outdoor lighting circuits up to 480V AC. It suits electricians and facility managers who need automatic dusk-to-dawn control for commercial or industrial fixtures.

Sustained load behaviour

The switch handles continuous operation across a temperature range of -40 to 140 degrees Fahrenheit. Its SPST contact form supports up to 15 A for incandescent loads and 10 A for ballast loads, with a maximum wattage rating of 7,500 W.

Thermals noise and power draw

The polycarbonate housing carries a raintight enclosure rating and includes a gasket and lock nut for weatherproof mounting. The unit operates silently with no moving parts beyond the 180-degree swivel mount, drawing negligible power for the photocell circuit.

Questions about this item

How much heat does the 480V SPST switch generate when it runs continuously at 15 A?

The housing is rated from -40 to 140 degrees F, so the polycarbonate body handles the heat of a 15 A load without exceeding its temperature limit.

What conduit fitting must already be on site for the 1/2 in mounting to work?

A standard 1/2 inch conduit opening with a lock nut is required; the included gasket and lock nut seal the connection.

Will the 180 degree swivel photocontrol still trigger correctly if mounted beside an older HID fixture?

Yes, the 1.0 to 5.0 foot-candle on and 3 to 15 foot-candle off thresholds operate independently of the adjacent light source.
