Double Pole 63a Mcb

NBT1-63 series small air switch has skillfully set the threshold of closing force of the operating handle in the products with higher rated current level (50a and above). Only when the operating force reaches a certain value, In order to make the contact close and make the contact close at a certain high speed, the influence of human factors on the contact closing speed is relatively eliminated, the electric wear loss of the contact is reduced, and the service life and reliability of the circuit breaker are improved. The comprehensive effect of NBT1-63 series small air switch is characterized by good current limiting characteristic, short arcing time, long service life and reliable performance.

FAQ

Q1: How many amps does it take to trip a 15 amp breaker?

A1: An important note to remember is that circuit breakers can only handle about 80% of their overall amperage. That means a 15-amp circuit breaker can handle around 12-amps and a 20-amp circuit breaker can handle about 16 amps.

Q2: Is it hard to replace a breaker switch?

A2: Although the process is not difficult—in fact, it's considerably easier than many routine wiring projects—the main power bus bars will be exposed as you replace a circuit breaker and there is a danger of serious shock if you're not careful.

Q3: What does a tripped circuit breaker mean?

A3: An overloaded circuit is the most common reason for a circuit breaker tripping. It occurs when a circuit is attempting to draw a greater electrical load than it is intended to carry. Hence, the breaker or fuse is intended to trip or blow before the circuit wires can heat to a dangerous level.

Q4: Does a breaker box need to be grounded?

A4: Without a grounding wire, the circuit breakers on your electrical panel board may not work properly. Because the wire touches the metal enclosure, the circuit would not be broken and the circuit breaker would not trip to cut power to the circuit. If you touched the metal, you would be shocked.

Q5:How does your company do regarding the quality control?

A5: Quality is priority. We always attach great importance to quality control from the beginning to the end of the production. IQC inspects the components, the patrol inspection is done during production and all the goods to be tested 100% before leaving the factory.
