GENERAL

RGM2L-225 MCCB incorporating residual current protection (hereafter simply referred to as breakers), the rated insulation voltage of the breakers is 690V. In the circuit of AC50Hz/60Hz, rated working voltage 415V , rated current from 125A to 225A, the breakers take the role of infrequent turn-on or turn-off .The breakers have overload and short-circuit protection devices ,also can protect from get an electric shock and leakage of electricity as well as fire caused by damage of insulation and trouble of grounding.

The breakers could be installed vertically or horizontally.

The breakers have isolating function and its corresponding symbol is shown as .

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 2000m.

The relative humidity of the air does not exceed 50% at a maximum temperature of +40℃ , higher relative humidities may be permitted at lower temperature,e.g.90% at +20℃. Special measures may be necessary in cases of occasional condensation due to variations in temperature.

Pollution degree 3.

Installing category: III for the main circuit, and II for other auxiliary and control circuits.

Be suitable in electromagnetic environment A.

There must be not any explosive medium, and there must be not any gas which would corrode metal or any conducting dust which would destory the insulation

The place would not be invaded by rain and snow.
