KPU temperature controls are temperaturecontrolled electrical switches, which are applied for regulation and safety monitoring of refrigeration and air conditioning systems. KPU sensors are available with vapor charge or with adsorption charge.Temperature controls with adsorption charge are widely used to give frost protection, while vapor charged sensors are used where small differential is required. All KPU temperature controls have a single pole double throw (SPDT) contact system. The position of the switch depends on the thermostat setting and the bulb temperature.

Features: Wide temperature regulating range allows use in low, medium, and high temperature refrigeration application and air-conditioning systems. Snap-action electrical contacts minimize chatter, bounce and wear, and ensure long-term electrical and mechanical reliability. Fingertip manual trip feature allows contact function testing without tools. Easily replaces other manufacturers’ temperature controls. Ultra-short bounce time. Long operating lifetime. Vibration and shock resistant • SPDT switch allows NC or NO function option as well as alarm capability. Automatic and manual reset versions available
