1. The leakage switch is damaged or the electrical appliance is grounded and short-circuited, and the zero line on the load side is mixed with the zero line on other circuits. 2. It is caused by unreasonable classification and section protection of the leakage protector switch of the  nut sorting machines . 3. Line faults, leakage, short circuit, wiring errors, etc. will cause tripping. 4. The switch is overloaded, and the rated current selection of the switch does not match. 5. The live wire on the load side of the switch is grounded, and the neutral wire on the load side of the leakage switch is grounded, resulting in a trip. Solution: 1. Select the leakage action current and action time of the leakage switch to be greater than the action current and action time of the upper level leakage switch. 2. Check whether the leakage switch is damaged, and replace it if damaged. 3. Check the insulation of the circuit on the load side of the leakage switch, and check whether the sensitivity of

When many customers choose  ​Industrial PC  online, due to the variety of products on the market, many companies make a lot of hype about their product copywriting, causing great trouble to customers when choosing.
