Control Relays

Schneider Electric’s relays detect abnormal conditions allowing corrective action before serious and costly breakdowns occur

Image of Schneider's Control RelaysSchneider Electric’s control relays monitor and detect abnormal operating conditions concerning phase, current, voltage, liquid level, frequency, speed, temperature, and pump control. The relays inform users of the abnormal condition and allow them to initiate the necessary corrective actions before serious and costly breakdowns occur. By monitoring energy network statuses, users can enable both electrical and mechanical load control. Schneider Electric’s control relays are suitable for a wide range of applications, such as hoisting, packaging, lifts, textile, pumping, and water. They are available in the 831 series voltage sensing relays (120 VAC, 240 VAC, and 24 VDC) and the 841 series current sensing relay (1 A to 8 A).
