Application

KPU thermostats are used for regulation and to ensure safety 

in refrigeration, freezing, air conditioning, ventilating and 

heating systems.

KPU thermostats are available with vapor charge or with 

adsorption charge.

All KPU thermostats are fitted with Single-Pole Double-Throw 

(SPDT) switches.

For large a.c. motors and for all d.c. motors, KPU is installed 

in the control circuit. For single phase ac motors, KPU 

is installed in the line voltage supply to the motor.

The standard KPU enclosure is rated NEMA 1. 

NEMA 1 is obtained when the thermostat is mounted on a flat 

surface. When mounting KPU on a bracket, cover all unused 

holes.

 The switch differential is dependent on range settings. Low range settings increases the differential. 

   High range settings decreases the differential. Use the graphs on page 3 to determine the correct differential setting.
