Summarization:

KXM2LE series residual current protected circuit breaker, its rated isolating voltage is 800V, apply to circuit with AC50Hz, rated working voltage 400V, rated current till 800A for infrequent conversion and electric motor infrequent start. Circuit breaker have overload, short circuit and under voltage protection function, can protect circuit and power supply apparatus from being damaged, meanwhile, can provide indirect contact protection to human, also can provide over current protection to non-detectable but long existed ground fault which may have fire risk. Rated residual operation current 30mA circuit breaker have additional protection function to direct contact person while other protection apparatus have fault.

◎Circuit breaker have small volume, high breaking capacity, short arc, anti-shake etc features.

◎Circuit breaker can be installed vertically or horizontally

◎This product according to below criteria:

IEC60947-1 and GB14048.1-2006

IEC60947-2 and GB14048.1-2008

◎Circuit breaker suitable for isolating , express code is " "

Normal working and installation criteria:

◎Surrounding media temperature can't higher than +40℃ or lower than -5℃; and average temperature in 24 hours can't exceed 35℃(except special ordering)

◎Installation place relative humidity can't exceed 50% while max temperature is +40℃,higher relative humidity is acceptable in lower temperature, for example relative humidity can reach 90% at 20℃,should adopt special measure when have condensation dewdrop which caused by temperature changing.

◎Humid tropical type circuit breaker relative humidity can't exceed 95% at +25℃;

◎Pollution degree: III

◎Main circuit of circuit breaker installation type is III, auxiliary circuit and control circuit (non connect to main circuit) installation type is II

◎Circuit breaker apply to electric magnetic surrounding A

◎Humid tropical circuit breaker can resist humid tropical, smoke, mycete affect.

◎Circuit breaker should install in the place without explosion risk, without conducting dust, unable metal corrosive and non-damage isolator

◎Installation place can't hit by rain, snow directly

◎Circuit breaker should install according to instruction.

Accessory

◎Inner accessory:

According to user's demand circuit breaker can lead wire directly(wire length is 1250px, special request should be informed when ordering), or install additional wire terminal.

Note: when rated control power supply voltage is DC24V, have 2 solutions:

Solution 1:Adopt DC24V shunt trip mechanism, but should according to below criteria: copper wire max length(both wire length) should according to below table, trip mechanism wire connecting terminal power supply power minimum need 50W

Solution 2:Adopt 24V middle relay control AC230V or 400V shunt trip mechanism, middle relay contact volume should not less than 1A.

 Warn: Undervoltage trip mechanism need power on firstly, then circuit breaker can be switch ON/OFF, otherwise circuit breaker will be destroyed.
