Thermostat 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 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 at surface with all unused holes covered.
