The energy after fully charging 1 PCS 470uF/50V ±20% capacitor with +15V DC voltage can trip the electromagnet under the control of manual switch. Each PCS is measured 20 times, and there is no normal tripping phenomenon. The reset force of the spring dynamometer test is: 26±2N

0~7V voltage charges the 220uF capacitor, the capacitor is discharged once, and the release must not trip
