Product Description

LDM9 CM3/CM1 Plastic Molded Case Circuit Breaker (MCCB) is one of the new circuit breakers developed by our company using internationally advanced design and manufacturing technology.

Its rated insulation voltage is 800V, suitable for AC 50Hz, with a maximum rated working voltage of 690V (LDM9-63 is 400V), and a rated working current of up to 800A, used for infrequent switching of circuits and infrequent starting of motors. It has overload, short circuit, and undervoltage protection functions, which can protect the circuit and power equipment from damage.

This MCCB complies with the following standards:
IEC60947-1 and GB/T14048.1 General rules
IEC60947-2 and GB/T14048.2 Low-voltage circuit breakers
IEC60947-4 and GB/T14048.4 Contactors and motor starters
IEC60947-5.1 and GB/T14048.5 Electromechanical control circuit devices
 

Terms of use

Ambient Air Temperature:-5ºC to +40ºC , the average temperature for 24 hours does not exceed +35ºC .

Installation Location:The altitude shall not exceed 2000m.

Atmospheric Conditions:The relative humidity of the air should not exceed 50% at a maximum temperature of +40 ºC . At lower temperatures, higher relative humidity is acceptable, such as reaching 90% at 20ºC . It is important to consider the condensation on the product surface due to temperature changes.

Pollution Level:III

Installation Category:The circuit breaker main circuit and undervoltage release coil are used for installation category . The auxiliary circuits and control circuits are installed in category III.

MCCB can withstand the effects of humid air, salt spray, oil mist, mold, and nuclear radiation.

The maximum inclination of MCCB installation is ±22.5° .

MCCB can operate reliably under earthquake conditions (4g).

MCCB should be installed in a location that is free from explosion hazards, conductive dust, ametal corrosion and insulation damage.

MCCB should be installed in a place that is not exposed to rain or snow.
