Precise current sensing: adjustable sensing range from 2 to 30 A AC for reliable, load tailored switching in a wide range of equipment. Self powered operation: integrated power supply powers the switch itself, eliminating the need for an external source in challenging environments. Quick status check: built in LED indicator provides immediate visual confirmation of operating state. Durable construction: enclosure made from self extinguishing ABS with advanced tube technology; resistant to heat and chemicals for long term use. Compatibility and performance: designed to switch AC loads with stable performance; suitable for panel mounting and standard control circuits. Use scenarios: Industrial automation panel: monitor motor loads and switch control circuits based on current. Machine safety interlock: cut power when current exceeds safe levels to protect equipment. Building HVAC or lighting control: regulate current loads to improve energy efficiency.
