NBT1-63 series small air switch adopts a large arc extinguishing chamber, and the arc motion track is connected with a large arc iron arc striking piece, which reduces the resistance of arc movement and prevents the arc from stopping in the middle of the way. There are more iron grid pieces (13 pieces), and the arc is cut, cooled, extinguished, and the multi-layer mesh iron grid is used at the arc nozzle to further cool and extinguish the arc, basically ensuring zero arc flashover and effectively preventing the occurrence of short-circuit of arc light between the poles; both sides of the arc chamber are provided with multi-layer mesh iron grid With the protection of special organic materials, a large amount of insulation vapor is produced under the high temperature of the arc, which makes the arc resistance rise and the voltage increase, which provides a strong guarantee for the rapid extinction of the arc. The insulation materials on both sides also effectively prevent the arc from burning the shell, ensuring the high insulation performance of the product.

FAQ

 

Q1: How many outlets can be on a 30 amp breaker?

A1: There is no limit to how many receptacles can be put on a circuit in a residence. In a commercial setting there is a limit to how many receptacles can be on a circuit but 120 volt 15/20 amp receptacles still cannot be on a 30 amp breaker. Receptacles must be 30 amp rated such as is used for an RV.

 

Q2 : How many circuit breakers does a house have?

A2: Most homes ideally have 100 or 200-amp breaker boxes depending on the amount of electricity that the panel needs to handle and the number of circuits that are added to the main circuit breaker panel.

 

Q3: Could you do OEM for us?

A3: Sure, we accept OEM and ODM order, please supply with the letter of Authorization for the brand.

 

Q4: Why did the power go out in only one room?

A4: The most likely cause is a tripped breaker. This can happen when the electrical circuit is overloaded, or a defective appliance or damaged cord short-circuits the system. First, you need to unplug all the appliances in the room, since one of them likely caused the safety device to blow.

 

Q5: Do you have to reset breaker after power outage?

A5: If the trouble is a general power outage, all you can do is call the power company. … Then, if you have a circuit breaker panel, flip all the breakers to the OFF position. Once the breakers are off, reset the main breaker to the ON position. One by one, trip the branch circuit breakers back on.
