Self powered operation No external power supply is required. The switch powers itself from the monitored AC current, simplifying installation and reducing wiring complexity for industrial and automation applications. Adjustable current range Built in potentiometer sets the action current from 0.2 A to 30 A AC. This allows precise thresholds for low sensitivity or higher load requirements, delivering reliable performance across a variety of monitoring tasks. Instant status visibility with LED An integrated LED provides immediate visual feedback of the switch status. This facilitates quick troubleshooting and real time monitoring in fast paced environments. power contactless switching The device uses a power MOS tube for efficient contactless switching, eliminating wear and tear on mechanical components. It offers robust reliability and fast response with millisecond level performance. Use scenarios Motor and equipment protection on an automation line Set the action current to automatically disconnect or signal when current exceeds the threshold, protecting motors, pumps, and other power circuits without external power sources. Energy management and automated control Use as a sensing element to trigger controls or log current usage on production lines, enabling more effective energy management and simplified automation. Rapid fault detection in industrial equipment Real time current monitoring with clear LED indication helps quickly identify abnormal loads, supporting preventive maintenance and minimizing downtime.
