- Q:Circuit breaker generally choose what ah?
- Leakage protection is protected by a relative leakage or electric shock current that occurs within the detected grid and is fully protected as a trip signal and electrical trip task.
- Q:What is the specific function of the auxiliary switch on the circuit breaker switch?
- Used to control, protect, adjust, measure and monitor the parameters of the circuit and the working conditions of each component.
- Q:The difference between the leakage switch of the air switch circuit breaker
- Mainly used for short circuit and overload protection. General 1P1P plus N or 2P. 3P or 4P, etc.
- 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.
- Q:What type of switch circuit breaker has undervoltage protection
- For example: Model DZ10-100 / 330 circuit breaker with over voltage, undervoltage protection function, from its model in the symbol / behind the second 3
- Q:Low-voltage circuit breaker is what can be broken and under normal conditions of the circuit
- the emission junction and the collector junction between the almost no current, the equivalent of 5.0V and R10 disconnected
- Q:How is the circuit breaker connected to the circuit system diagram?
- Disconnector: similar to the knife switch, no to prevent overcurrent, short circuit function, no arc device; can not disconnect the load current and short circuit current
- 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:How to distinguish between disconnectors, circuit breakers?
- Because it does not have a special arc extinguishing device, can not cut off the load current and short circuit current.
- Q:Is there a circuit breaker in the circuit
- However, the use of fuses and circuit breakers in the use of attention must be clear
