Littelfuse LSRXC Current Sensor Relay

The LSRX/LSRX-C Series are AC current sensors that activate an output contact when 4.5 Amps or more are present. Designed for motor operation indication and machinery monitoring, these self-powered, cost-effective relays eliminate the need for control voltage by drawing power from the monitored wire. They feature quick-connect terminals, visual status indicators, and provide isolation between loads and control circuits. Suitable for AC loads up to 200A, they are ideal for interlocking fans, compressors, and stage control for pumps or chillers. Rugged, reliable, and easy to install, these sensors are UL and IEC certified, supporting various current sensing applications in industrial environments.
