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:Circuit system diagram and circuit breaker connection
, but in the maintenance can manually disconnect the circuit to ensure that maintenance personnel personal safety
Q:How long does the circuit breaker last?
Functional switchgear is the use of not only has a switching function, but also has other special features of the switch (such as circuit breakers, speed switches, delay switches, etc.) control of electrical appliances
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 are the differences between switches and circuit breakers?
And because of its arc extinguishing device and internal structure, he can also load with the gate
Q:Is the MCB switch a circuit breaker or a component on the circuit breaker?
The determination of the total switch circuit breaker in the household distribution box is determined by the sum of the rated current of all the branch circuit breakers in the distribution box
Q:Is the circuit breaker in the circuit necessary?
when the current is slightly larger, will only cut off the other two phase to produce too much electric current Arched open
Q:Circuit problem! Hurry Miniature Circuit Breaker!
Circuit breaker trip and leakage instructions do not pop up, indicating that the leakage is not a jump or jump
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:What is the length of time that the circuit breaker can delay?
that is to say the greater the overload the greater the tripping time, overload current tripping time is long
Q:Home no electricity corridor switch the total switch circuit burned how the matter
such as wiring crush is not strong, resulting in electricity when the heat, accumulated to a certain situation, burn the switch.
