Temperature-Controlled Outlet Splitters

NEMA 5-15 Plug

NEMA 5-15 Socket

Automatically power heating and cooling devices on and off when temperatures rise or drop. With two outlets each, you can run multiple devices. Plug them into a standard wall outlet.

Heating outlet splitters turn the power on when your space drops below a set temperature. They cut the power once temperatures warm up. Splitters that turn on at 20° F are often used to switch on engine and battery heaters when working in cold temperatures. Splitters that turn on at 35° F work best with heaters to warm a space and prevent freezing.

Cooling outlet splitters turn the power on when your space rises above a set temperature. They’re often used to turn on fans or other devices for cooling, ventilation, and air circulation. These outlet splitters cut the power once temperatures cool off.
