Operates on the principle of mutual induction for accurate AC current detection. Outputs a switch signal that can be configured as normally open (N.O.) or normally closed (N.C.). Equipped with an LED indicator for real-time status visibility. Housed in durable, heat-resistant ABS material for enhanced safety and performance. Monitoring current range of AC 0.2-30A with a response time of less than 200ms. The AC current sensing switch is designed to provide reliable detection and control of AC currents. It isolates the current and outputs a switch signal, ensuring superior performance compared to traditional transformers and thermal protectors. With a compact size of 65x47x25mm, it operates effectively in a wide temperature range of -20 to 55°C. The device is ideal for various applications requiring current monitoring and control.
