## Description

Model: DZ47B 2P 100A Rated Operating Voltage : DC12V-240V Poles: 2P Rated Current: 100A breaking capacity: 4 kA Ics=Icu Trip Curve: B Mechanical Life: 10,000 times Electrical Life: 4,000 times Installation Method: 35MM DIN Rail Standard: IEC60898 / GB10936 Operating Temperature: -30℃ to +70℃ Operating Altitude: 2000 MeterCircuit 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
