| Note: 6A no thermal protection The N-pole of four-poles breaker is sifed at the right side of the product has four types: Type A: No current trip-lease on N pole which making all the time, not closing and opening with the other three poles. Type B: No current trip-release on N pole which closing and opening with the other poles. Type C: With current trip-release which closing and opening with the other three poles. Type D: With current frip-release which making all the time not closing and opening with the other three poles. |
- Q: s the MCB switch a circuit breaker or a component on the circuit breaker?
- or the sum of the maximum power that can be tolerated by the "wire diameter" in each circuit The Whether it is necessary to consider (need coefficient, power factor), if not, in that case only to consider.
- Q: What is the solution of the leakage circuit breaker always jumping?
- if it exceeds its rated current or leakage, primarily for home or office lighting and to ensure the safety of the person.
- Q: What is the choice of low voltage electrical circuit breaker?
- This feature is often useful when the circuit breaker and the system are exposed to the same heat source. In this case, the protection circuit can track the equipment at higher temperatures for enhanced wiring protection requirements
- Q: What is the difference between a circuit breaker and other switches?
- replace the contacts and components more convenient, and more used in the power side of the main switch
- Q: Discussion on the Selection of Circuit Breaker in Low Voltage Circuit
- especially in recent years, single-chip technology applications, Frame circuit breakers toward high performance, easy maintenance, network direction.
- Q: Is the zero line going through the circuit breaker?
- if there is a device leakage or short shell, circuit breaker (fuse) can not be broken, So that all the lines on the line of the device shell to bring the leakage voltage.
- Q: How to distinguish between disconnectors, circuit breakers?
- mainly used to disconnect the no-load current circuit, isolated power supply, in the sub-gate when there is a clear disconnect point to ensure the safety of other electrical equipment maintenance.
- Q: Why the high-voltage circuit is equipped with isolation switch and circuit breaker
- The high voltage isolating switch is designed to be able to secure a safe disconnect from the power point when the circuit breaker is overhauled
- Q: Do you have a circuit breaker in the circuit?
- Of course, there are many problems in practical applications, this is just an example.
- Q: Short trip also tripped, overload also trip it?
- The element combination is mainly used for short circuit and overload protection. Generally divided into 1P 1P plus N open air or. 3P or 4P, etc.
