GENERAL

RGM3HU series moulded case circuit breaker (hereafter simply referred to as breakers), the maximum rated voltage of the breakers is DC1500V,and the maximum current is 800A.In the voltage of DC1500V,the maximum breaking capacity is 50kA,which can ensure reliable short-circuit protection of the system. 

The breakers could be installed vertically or horizontally.

The breakers comply with the demands of the following standards:

IEC60947-1 and GB14048.1  Low-voltage switchgear and controlgear——Part1：General rules.

IEC60947-2 and GB/T14048.2  Low-voltage switchgear and controlgear——Part 2：Circuit-breaker.

NORMAL SERVICE AND MOUNTING CONDTIONS

The ambient air temperature does not exceed ＋40℃ and its average over a period of 24h does not exceed ＋35℃,the lower limit of the ambient air temperature is －5℃.

The altitude of the site of installation does not exceed 5500m.

It is resistant to damp air(three-proof type).

It is resistant to the influence of salt fog and oil fog(three-proof type).

It is resistant to the influence of mold(three-proof type).

In a medium without explosion risk, and the medium is not enough to corrode the metal and destroy the insulation of the gas and conductive dust.

Note: The three-prevention products should be specially customized, please indicate TH.
