AC Current Sensing Switch 0.2–30A Self Powered Monitoring Relay, Non Intrusive Current Sensor with Built in Relay Output for Electrical Panel Protection and Load Monitoring

• Multifunctional Control: AC Current Sensing Switch enables direct control of industrial automation devices including flash units, buzzers, relays, microcontrollers, and power loads without signal conversion hardware. Supports 5–200A detection range and 120V/240V AC systems. Integrates into existing control loops for immediate equipment response. Reduces wiring complexity in factory machine interfaces and maintenance panels.
• Wide Current Detection Range: AC Current Sensing Switch delivers precise real-time monitoring across 5 to 200 amps (200A = 440A peak), compatible with standard North branch circuits. Features ±3% accuracy at 60Hz and operates from 45–400Hz. Enables reliable load tracking for HVAC compressors, lighting arrays, and motor starters in commercial buildings.
• Self-powered Passive Technology: AC Current Sensing Switch uses electromagnetic induction to generate operating power directly from measured current—zero external wiring or batteries required. No power supply footprint or voltage compatibility checks needed. Simplifies retrofit installation in tight enclosures like breaker panels and junction boxes.
• Extensive Industrial Applications: Widely used in substation, frequency control device, inverter device, electrolytic plating, electric locomotive, street lamp monitoring, coal mine and other need current monitoring automation industry.
• Advantages: Compared with traditional transformer and thermal protector, it has the advantages of , and long service life.
