Technical Data

◆Number of poles:1,2,3,4,1+N,3+N
◆Nominal current In(A): 1,2,3,4,6,8,10,13,16,20,25,32,40,50,63
◆Characteristics:
◇B The short-circuit release is to be set up to 3 In through 5 In.It serves especially for protection of circuits with such devices which do not cause any current surges(lights or socket circuits etc.)
◇C The short-circuit release is to be set up to 5 In through 10 In.It serves especially for protection of circuits with such devices which cause some current surges(groups of bulbs, motors etc.)
◇D The short-circuit release is to be set up to 10 In through 20 In. It serves especially for protection of circuits with devices which cause high current surges(transformers,double-pole motors,motors with heavy start etc.)
◆Nominal voltage:
◇1P (single-pole)~230/400V 50/60Hz
◇3P (three-pole)~400V 50/60Hz
◆Rupturing capacity:
◇EN60898-10,000A(nominal short-circuit and operational rupturing capacity)
◆Protection:IP40 for a sole MCB with its design, it protects against a hazardous finger or instrument touch as well as against very small foreign objects; It is without any protection against water leakage (water protection is to be solved with design of the switchboard casing)
◆Ambient temperatue: -5oC to +40oC pursuant to EN60898
◆Gauging temperature:+30oC pursuant to EN60898
◆Max.pre-inserted fuse:100AgG(>10kA)
◆Mechanical lifetime:≤20,000 cycles
◆Electrical lifetime:≤8,000 cycles
◆Fastening:By means of an unique snap mechanism(with arrestment in final positions)the carrying DIN strip EN50022,width 35mm, or even onto the falt surface by means of screws.
◆Removal form the DIN strip:
◇By means of an unique auxiliary snap mechanism, the MCB誷 can be removed even from a row of devices mutually interconnected by a forked or reed rack strip without necessity to dismantle the whole interconnecting strip.

◆Input terminals:
◇Clip terminals(with barrier layer), snap-locked against the worse input of a conductor
◇The input and output can be interchanged
◇They enable more conductors as well as interconnecting strips to be connected
◆Connect ability of conductors (Maximum cross-sections):
◇35mm2 solid conductor
◇25mm2 stranded conductor
◆Terminal protection:IP20
◆Tightening moment for terminals
◇2Nm(combined slotted-head screw)
◆Manufacture standard
◇EN60898,same to IEC 60898
◆Selectivity calss:3
◆Colored levers:
For better distinction among circuits in the switchboards,we supply also miniature circuit breaker with distinction of nominal currents by means of colored levers corresponding to the colors of turn fuses

Q: s 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: 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: 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: Isolation switch, circuit breaker, open the three What is the difference between ah: Circuit Breakers High-voltage circuit breakers, and low-voltage circuit breakers are an electrical protection device, and its type is very much with an arc extinguishing device

Q: Do you have a circuit breaker in the circuit?: the fuse is only Disconnect the phase, while the remaining two phases continue to supply power, resulting in motor phase loss burned.

Q: Short trip also tripped, overload also trip it?: second with overload and short circuit protection function ..... leakage protection RCD

Q: Why the first break circuit breaker, after the isolation switch off it?: can not disconnect the charged circuit, so the disconnector should be used in conjunction with the circuit breaker.

Q: Circuit breaker main circuit control power, how to wiring?: Otherwise you should use a larger capacity circuit breaker or technical transformation, reduce the installation of short-circuit capacity. Or on the circuit breaker capacity transformation

Q: How to choose the home of the circuit breaker air switch?: Socket circuit to be installed leakage protection device to prevent leakage of household appliances caused by personal shock accident.
