� APPLICATION RANGE AND ENVIRONMENT CONDITION
TRM1 Series moulded case circuit breaker (below for short
MCCB), is applicable circuit of AC 50Hz (or 60Hz) ,rated
insulation Voltage 690V,rated operating Voltage up to 690V, rated
operating voltage up to 250V(DC).The rated operating current
12.5A-800A.For distribute energy of elecricity and infrequent
making and breaking circuit, and infrequent staring of motor (rated
operating current up to 400A) at normal condition they are provided
with the function of the protection against overload and short-
circut and undervoltage.
The MCCB comply wi th s tandard of IEC60947-2,
GB14048.2,GB14048.4 and so on.
MCCB are suitable for vertical and horizontal mounting.
The MCCB can be reliably operated under the following
conditions.
1. The altitude not exceeding 2000m.
2. The ambient temperature is from+40�to-5�;
3. In medium where is no explosive danger and air or dust which
may cause corrosion of metal or weakness of insulation.
4. Where is no erosion of rain or snow.
5. Pollution degree 3.
6.Overvoltage category III.
