Stable performance Designed for precision and reliability, this current sensing switch simplifies wiring and improves protection compared with traditional transformers and thermal protectors. Integrated power supply Operates with a selfsufficient power supply, so it runs without an external source and remains functional even in challenging magnetic environments. LED indicator light Integrated LED shows the operational status, allowing quick monitoring of input current in the 2 to 30 A AC range. Robust construction Built with tube technology and housed in selfextinguishing ABS material, it resists heat, acids, and alkalis for durable, safe operation. Key benefits Simplifies setup and provides reliable overcurrent protection without bulky external components Independent power supply for use in environments with magnetic interference Clear status indication and a wide 2–30 A AC current range Durable, heat and chemical resistant construction suitable for demanding environments Compatible design and form Compact, easytofit form factor for standard panels and enclosures Suitable for low, medium, and continuous load applications Tube technology and ABS housing emphasize safety and longevity Practical applications Workshop power protection: monitor tool startup surges and quickly cut off on overcurrent Motor or pump panels: reliable protection in environments with electrical noise or magnetic interference Lab bench or test setup: independent current sensing and status indication for experiments and demonstrations
