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: How to protect the leakage protector leakage protection?
- Capture leakage, electric shock and other ground fault current. Trip and strokes according to its breaking reaction time cut off the power
- Q: What is the solution of the leakage circuit breaker always jumping?
- may be caused by the wire. Leakage switch installed in the use of equipment before the better
- Q: What is the difference between open air and circuit breakers?
- China Electric Trading Network in the previous reports introduced the air switch is our usual familiar, it is the correct name called air circuit breaker. Air circuit breakers are generally low pressure, that is rated operating voltage of 1Kv
- Q: What are the differences between switches and circuit breakers?
- Generally in the power supply system, the isolation in the upper part of the circuit breaker, so the order of operation: closing
- Q: Discussion on the Selection of Circuit Breaker in Low Voltage Circuit
- Frame circuit breakers have reached this standard). Also in the segment ability,
- Q: Why the high-voltage circuit is equipped with isolation switch and circuit breaker
- The circuit breaker has an overload protection function that can operate with current. But the contact is covered by the arc extinguishing device, the break point is not visible.
- Q: How to switch from the circuit breaker switch button, the difference is short circuit protection or overload protection?
- The circuit breaker is called open SPACE> This is a switch that can automatically protect the low voltage distribution <aka air circuit breaker switchgear
- Q: Short trip also tripped, overload also trip it?
- second with overload and short circuit protection function ..... leakage protection RCD
- Q: Where will the circuit breaker auxiliary contacts be used? ,
- general electromagnetic molded case circuit breaker for the non-selective circuit breaker, only long delay and instantaneous two kinds of protection, electronic molded case circuit breaker has a long delay
- 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.
