The KP Thermostats are single-pole, doublethrow (SPDT) temperature-operated electric switches.
They can be connected directly to a single-phase AC motor of up to approx.
2 kW or installed in the control circuit of DC motors and large AC motors.
The KP Thermostats are used for regulation, but can also be seen in safety monitoring systems.
They are available with vapour charge or with adsorption charge.
With vapour charge the differential is very small.
The KP Thermostats with adsorption charge are widely used to give frost protection.
