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 tted 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 at
surface. When mounting KPU on a bracket, cover all unused
holes.

The switch dierential is dependent on range settings. Low range settings increases the dierential.
High range settings decreases the dierential. Use the graphs on page 3 to determine the correct dierential setting.
