The cosPhi monitor is used to detect an underload. The response value and the response time can be set. It can also be used in conjunction with a frequency converter (frequency 2 to 200 Hz). The monitoring is done by detecting the phase shift between...

The thermistor relay is used as a protection relay for motors against thermal overload (inadmissible heat-up). This warming may occur due to mechanical overload on the shaft or when operating the motor with unacceptable voltages. A PTC (PTC) is used as...

The speed and V-belt monitor is used to monitor rotational movement (underspeeds) on motor or belt-driven shafts. Inductive proximity switches are used to measure the speed. The impulse generation at the sensor is generated contact-free by switching cams,...
Monitoring relay for the monitoring of a three-phase connection for asymmetry, phase loss, phase sequence error as well as over- and undervoltage. With external fault acknowledgment.Connection with screw terminals, adjustable delay, unbalance, selectable...
