Monitoring relays
Monitoring relays are electrical components used to continuously monitor critical parameters in electrical systems, such as voltage, current, phase sequence, asymmetry, and frequency. They protect equipment and installations by quickly responding to deviations that could lead to operational disruptions, damage, or safety hazards.
If a measured value exceeds a preset threshold—for example, in the case of a phase failure, undervoltage, or overcurrent—the relay activates to disconnect the load or trigger an alarm. Monitoring relays are used in a wide range of applications, including industrial control panels, power distribution systems, HVAC equipment, and renewable energy setups.
We offer a comprehensive selection of high-quality monitoring relays from our trusted partner Tele Haase, a leading manufacturer in the field. Their relays combine precision, reliability, and ease of use to meet the demands of both basic and advanced applications.
