Application Range
FCM7(DPN)-32 series miniature circuit breaker is used for single phase circuits with AC 50/60Hz and rated voltage up to 230V AC. It’s applied to protect overload and short circuit of electric circuit, and also widely used as branch switch for family, hotel, apartment, hospital and industrial enterprise. The ideal product for residential field as protection switches for power distribution.
Structure Feature
FCM7(DPN)-32 series miniature circuit breaker has some advantages like: high breaking capacity, small size, compact structure, two poles (P + N) with 18mm width of two moulds, cutting off phase line and N line at the same time. And N pole has feature of first switching on then breaking that can avoid prison risk caused by incorrect connection of phase line and N line or voltage to ground of N line.

- Q: Is the isolator and circuit breaker able to switch to each other?
- such as the use of broken break with a visible breaking point of the circuit breaker, may not be isolated Switch "disconnector can be replaced by a short circuit (technical information can be accessed)
- Q: Low-voltage circuit breaker is what can be broken and under normal conditions of the circuit
- led and so can not light The Is the base high level, N tube is generally off, low level, N tube open
- Q: How is the circuit breaker different from the air circuit breaker?
- Upstairs said the air switch is a kind of circuit breaker. The switch is a switch that can turn on and off the load current; the disconnector is an electrical device that isolates the power supply and can not turn on and off the current (except for the voltage)
- Q: How to distinguish between disconnectors, circuit breakers?
- It is a no arc device switch device
- 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: Short trip also tripped, overload also trip it?
- who works in a simple sentence, will produce heat when any electrical work and power are proportional to the heat for the degree.
- Q: Circuit breaker main circuit control power, how to wiring?
- In use, the circuit breaker should be cut off the capacity of the installation should be greater than the maximum short circuit capacity
- Q: Switch switch, disconnector, circuit breaker difference? What are the possible functions of each?
- Circuit breaker, it can be on the line voltage, current and other parameters to monitor, alarm, action, not only as a break poin
- Q: What type of switch circuit breaker has undervoltage protection
- Circuit breakers with overvoltage and undervoltage protection:
- Q: How to choose the home of the circuit breaker air switch?
- air conditioning circuit, separate wiring, when one of the circuit (such as the socket circuit) failure, the other circuit can still be normal power supply.
