Product Description
Application
KXM1LE-63 series electric leakage miniature circuit breaker mainly apply to the circuit with AC 50Hz/60Hz, rated voltage 400V and single phase 230V, rated current 3A-63A, this series circuit breaker have electric leakage protection, electric shock protection, overload protection or short circuit protection etc function, according clients request, additional overvoltage protection also is available, safeguard personal security and prevent accident which caused by equip electric leakage, also can be protected circuit for overload or short circuit, used for circuit infrequent breaking or converting in normal condition, electric leakage circuit breaker with rated residual operating current 30mA can direct protect people from electric shock.
This series miniature circuit breakers meet the following criteria:
GB16917,GB10963,IEC61009,IEC60898
Model No. and meaning:
Structure summarize:
KXM1LE-63 electric leakage miniature circuit breaker consist of KXM1-63 miniature circuit breaker and electric leakage tripping mechanism. Electric leakage circuit breaker is current operation digital type circuit breaker, consist of zero sequence current mutual inductor, electronic components plate, electric leakage tripping mechanism circuit breaker and overload protection & short circuit protection circuit breaker.
Normal working and installation criteria:
1.Surrounding temperature range:
◎Max:+40℃, and 24h's average temperature should lower than +35℃
◎Min:-5℃
2.When client's surrounding temperature higher than +40℃ or lower than -5℃, client should communicate with our company to get a solution.
3. The altitude of installation place should lower than 2000m.
4.atmospheric conditions:
Atmospheric relative humidity should lower than 50% when the temperature is +40℃, higher relative humidity is acceptable when the temperature lower than +40℃, max relative humidity can reach 90% when the temperature at +20℃, we have special policy in condensation condition which may caused by temperature changing. Should communicate with our company to get a solution when beyond the criteria.
5. External magnetic field of any direction of the installation place can't exceed earth magnetic for 5 times.
6.Pollution degree: II degree
7.Installation type: II degree or III degree
8.Installation place shouldn't have obvious impact, no dangerous explosion neurogen, no etchant gas, and can't hit by dust, rain or snow
9. Vertical installation on the standard DIN rail.

Note: Wire connecting adopt clamp connection terminal, can connect guide line ≤25mm2
Warns: Rated electric leakage operation current lower than 30mA have safeguard personal security function.
Overall and installation size:
Wire connection diagram:
Bimetal: Actually, it contains three metals iron, copper, cadmium, galvanized. Three metals with different coefficients of thermal expansion, bending cause thermal Pick reflect and making the breaker disconnect. This is the most import parts of the circuit breaker. The Bimetal is the use of different materials under different breaker amperage.
Coil: It's the important parts for the reaction of the Magnetic Trip. It's always 9 ring. As a matter of fact, the number of Coil with Different Amperage.For example, 1A reaches over 100 ring, and 63A is used to 56 ring. The Diameter Thickness is also different for Amperage.
Action Contactor(Sliver Point): It's the main point for the Reaction of Trip. Under normal conditions, keeping closed. When overload and short circuit, It will be breaking.
Arc Chute: Playing a role in destroying the arc. Generally tend to produce a large number of Moving and Static Contactor from the contactor, arc, even emerge spark.
