Information

The 200A DC Contactor manufacturer tells you that the contact resistance of the circuit breaker of the DC contactor is not firm, which will increase the contact resistance between the acoustic circuit breakers, causing the surface temperature to be too high, so that the contact between the surfaces becomes point contact, so that there is no on-off state. 200A DC Contactor manufacturers tell you the reasons for this common failure are:

good price and quality 200A DC Contactor
1. The circuit breaker has oil stains, flowers and dirt.
2. Long-term application, the surface air of the circuit breaker is oxidized.
3. Electric crevice corrosion leads to defects, vibration lines or generation of metal material chip particles, etc.
4. Part of the fitness exercise is blocked. The reason why the DC contactor has a large flame when it is closed or disconnected and the solution
The solutions for the weak DC contactor connector are as follows:
1. 200A DC Contactor manufacturers tell you that oil stains, flowers or dirt on the circuit breaker can be cleaned with pure cotton cloth dipped in ethanol or gasoline.
2. The manufacturer of 200A DC Contactor tells you that if it is a silver or silver-based alloy circuit breaker, when the contact surface is converted into an air oxide layer or mildly scalded and blackened under the effect of electric isolation, it is generally not harmful to work, and ethanol can be used. And vehicle gasoline or carbon tetrachloride water solution cleaning. Even if the surface of the circuit breaker is burnt and uneven, only use a fine file to eliminate the splashing beads or vibration lines around it. Do not file too much to prevent the service life of the circuit breaker from being jeopardized. 200A DC Contactor manufacturers tell you that for copper circuit breakers, if the degree of scalding is mild, just use a fine file to repair and level the unevenness, but it is not allowed to use a fine sand cloth to polish and prevent quartz sand grains from leaving the circuit breaker If the scald is serious and the surface is depressed, be sure to replace the circuit breaker with a new one.
3. The 200A DC Contactor manufacturer tells you that there is a blockage in part of the fitness exercise, and it can be disassembled for maintenance.
