KPU 19
KPU 19 thermostats are used for temperature regulation in refrigeration, freezing, air conditioning, ventilating and heating systems.
KPU 19 thermostats are fitted with Single-Pole
Double-Throw (SPDT) or Single-Pole Single-Throw
(SPST) contact system.
The standard KPU 19 enclosure is rated
NEMA ~ 1.
NEMA ~ 1 is obtained when the thermostat is mounted on a flat surface with all unused holes covered.
