Data Sheet

Thermostat
Type KPU 19

KPU 19 thermostats are used for temperature
regulation in refrigeration, freezing, air
conditioning, ventilating and heating systems.

KPU 19 thermostats are tted with Single-Pole
Double-Throw (SPDT) or Single-Pole Single­Throw (SPST) contact system.

The standard KPU 19 enclosure is rated NEMA ~

1.

NEMA ~ 1 is obtained when the thermostat is
mounted on a at surface with all unused holes
covered.

Features

• Long operational life time

• Stable settings

• Reliable and robust SPST and SPDT contact
system

• Switching points can be set easily and
accurately using the range scale plate and
dierential adjusting knob.

• Terminals enable easy wiring

• KPU 19 easily replaces other manufacturers’
thermostats
