Product Introduction: SZC03 series AC current induction switch is designed and produced to solve AC current monitoring. It uses the principle of mutual inductance to isolate AC current by inducing AC through-core current, output a normally open or normally closed switching signal, and directly control various automated industrial control equipment Compared with traditional transformer, thermal protectors and other devices, using this device can not only obtain more accurate and timely control effects, but also greatly simplify Design, reduce costs, and greatly improve the overall competitiveness of the product.
