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: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: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:Is the MCB switch a circuit breaker or a component on the circuit breaker?
or the sum of the maximum power that can be tolerated by the "wire diameter" in each circuit The Whether it is necessary to consider (need coefficient, power factor), if not, in that case only to consider.
Q:Is the circuit breaker in the circuit necessary?
occasionally short-time overcurrent motor can withstand, but the fuse blown, but also affect the production.
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:The specific function and operation mode of the auxiliary switch on the circuit breaker switch
High-voltage circuit breakers generally have a number of auxiliary contacts, their on-off and circuit breaker main contact the same (or vice versa), so the secondary circuit
Q:Household leakage circuit breakers, circuit problems
do not know how the points. Maybe 2P, but I do not know. Four holes, up and down two, how to take this
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 common circuit switch called switch
Manual and electric operation are, with the development of microelectronics technology, the current part of the intelligent circuit breaker with a regional
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
