63 Amp Circuit Breaker Box OEM and ODM services
Focusing on the low voltage industry. we are professional manufacture of distribution box and junction box, which have been cetified with CE,ROHS and IK,HF. Regarding to making the box,we have more competitiveness not only on Zcebox products but also on OEM and ODM services.
63 Amp Circuit Breaker Box is mainly used as the main switch of terminal electrical appliances, and can also be used to control various motors, low-power electrical lighting, etc. This product supports overload protection and short-circuit protection and meets the standards of GB14048.3 and IEC947-3. The temperature of the application environment is also very wide, and the strength from severe cold to scorching heat is full of worry-free use.
It is more appropriate to choose a two-pole circuit breaker for the main power protection in a home environment, and use a single-pole protection; if the rated current of the circuit breaker is selected too small, the circuit breaker is likely to trip frequently and cause unnecessary power outages. If the selection is too large, The expected protection effect cannot be achieved.
In order to keep the main 63 Amp Circuit Breaker Box in good working condition, maintenance management must be strengthened.
1. Keep the air moist or dirty, and the pipes are not clean, which may cause the following consequences:
(1) The moist gas decomposes into mixed gases such as hydrogen and oxygen under the action of the arc, which destroys the insulation between the fractures after the main contact is broken. It is difficult for the arc or the arc to reignite, and it will cause the arc extinguishing chamber to burst in severe cases.
(2) Reduce the insulation strength of the supporting porcelain bottle and the cavity of the arc extinguishing chamber, causing creeping discharge.
(3) Foreign matter such as paint, rust and slag in the pipeline may block the air port, causing the main circuit breaker to malfunction and cause jamming.
(4) If foreign matter enters the arc extinguishing chamber, it may cause poor contact of the main contact, which will cause the non-linear resistor to burn due to long-term energization. In severe cases, it will cause the non-linear resistor porcelain bottle to burst.
Therefore, an oil-water separator is installed on the intake pipe of the air storage cylinder of the main circuit breaker, and there is a water drain valve at the lower part. The water should be drained regularly during maintenance to keep the air circuit clean.
2. Regular replacement of rubber parts
The main circuit breaker is a kind of pneumatic and electrical equipment with complex structure. Each component has high requirements on sealing performance. In order to ensure good sealing performance, rubber parts should be replaced regularly.
3. Regularly check the main components
