Circuit Breaker Purchase Instructions
The cause of the circuit breaker fire
1. The current is high and the cable is thin, and the cable heats up and causes a fire
2. Poor contact, the screws of the circuit breaker are not tightened, causing the screw part of the circuit breaker to heat up and catch fire (90% of the fire causes)
Note: Be sure to tighten the screws — important!!!
3. The quality of circuit breakers is poor. Our company selects A-level standard materials and flame-retardant shells for production. Each product is tested, and the quality pass rate reaches 99.5%.
4. Dust enters, humid environment; the circuit breaker is not waterproof and dustproof, try to use it in a waterproof box.
Note：If you find that the screw part of the circuit breaker is burned, 99% of it is because the screw is not tightened
How to choose the current of the circuit breaker
The current of the circuit breaker needs to be 20% larger than the working current. If the working current is 20A, Please choose 25A circuit breaker. If choose 20A, the circuit will trip and power off
