Product Description:

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:What is the difference between open air and circuit breakers?
The first two kinds of protection for the basic configuration of the air circuit breaker, the latter two for the optional function. So the air circuit breaker can also fault in the state (load short circuit, load over current, low voltage, etc.) cut off the electrical circuit
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:Home circuit breakers and how much air is open
According to the requirements of customers and decoration personality differences, combined with the actual situation of flexible distribution plan.
Q:How to choose the home of the circuit breaker air switch?
Modern home electricity should be in accordance with the bright circuit, power outlet circuit
Q:How to look at the circuit breaker capacity is how much?
The rated breaking current of the circuit breaker is three times the root number of the product of the rated voltage, that is, the blocking capacity.
Q:Is this an air switch or a leak protector?
The working principle is simple to say that any electrical appliances will be hot at work and the degree of heat and power into Proportional.
Q:Is it possible to switch the lamp directly with a circuit breaker?
Circuit breaker (English name: circuit-breaker, circuit breaker) is able to close, carry and break the normal circuit under the conditions of the current and can be closed, within the specified time to carry and break the abnormal circuit under the conditions of the current Switchgear.
Q:Leakage circuit breaker old jump how to do
Leakage protection The main role is to solve the leakage problem: how much current out of the phase line, the neutral line will come back how much current
Q:Is the isolator switchable with a circuit breaker?
the disconnector can not be used to turn on or off the current, it is only broken in the case of breaking the circuit breaker, to provide a "clear break point."
Q:What is the role of the circuit breaker?
the circuit breaker internal trip mechanism, there is a different coefficient of expansion when the two kinds of metal bonding bimetallic together,
