GW1-24 Isolation Switch

Selection

Operating conditions

The altitude above sea level: 2000m
The ambient air temperature: -40℃~40℃ wind speed does not exceed 35m/s.
The earthquake intensity does not exceed 8 degrees.
The working situation is without frequent violent vibration.
The installation site of ordinary type isolator should be kept away from
gas,smoke chemical deposition, salt-spray fog, dust and other explosive
and corrosive maters that affect seriously insulation and conduction
capability of the isolator.
Pollutioni proof type isolator is applicable to severe filthy conduction area
however, it shouldn't be any explosive matters and matters causing fire.
