About this item
- Self-Powered Operation with Adjustable Sensing: This current sensing switch requires no external power supply, operating independently through mutual inductance principles. With an adjustable action current range of 0.2-30A AC using a potentiometer, it provides flexible monitoring for various electrical applications without additional wiring complexity
- Fast Response with Reliable Performance: Featuring a high-power MOS tube contactless electronic switch, this sensor offers quick response times reaching millisecond levels. The switch can open and close without limitation, providing reliable performance for continuous monitoring and control of automation equipment
- Wide Application for Industrial Monitoring: Designed for AC current monitoring in industrial settings, this switch is suitable for substations, frequency conversion speed control devices, inverter equipment, and other electrical systems. It outputs normally open switching signals to directly control alarms, indicators, relays, or power load equipment
- Durable Construction with Isolation Protection: Housed in self-extinguishing ABS material with heat resistance and high impact strength, this current sensor features a straight-through design with isolation withstand voltage up to 2000V. The rugged construction ensures stable performance in demanding industrial environments
- Simplified Design for Cost-Effective Solutions: Compared to traditional and thermal protectors, this current sensing switch simplifies system design while providing accurate and timely control. It reduces component count and installation complexity, offering a cost-effective solution for AC motor overload protection and automation system monitoring
