Schneider Electric 841CS8-UNI Current Sensing Relay

Schneider Electric 841CS8-UNI is a current-sensing relay that monitors a single circuit and drives a SPDT output when the sensed AC current falls within the 0.8 A to 8 A range. It operates from a control supply of 24 to 240 VAC and provides a relay contact rated for 15 A at up to 240 VAC, enabling reliable switching of loads or signaling to automation equipment. The unit is designed for DIN mounting and uses a single timing scale, making it compact for panel or control cabinet installations. As part of Schneider Electric's 841 Series of current-sensing relays, the 841CS8-UNI is paired with other UNI variants to cover a broad spectrum of sensing ranges while offering consistent form factor and wiring. Typical applications include motor protection and control logic for pumps or fans, energy-management tasks, andPLC or controller signaling where a current threshold triggers downstream control actions based on real-time circuit current.
