Application
HR5 fuse-switch disconnector (hereinafter referred to as the switch) is mainly used in the distribution circuit with high short-circuit current and motor circuit where the rated voltage is AC 380V and 660V (45 to 62Hz), the conventional thermal current is up to 630A to serve as power switch, switch disconnector, emergency switch and exert the function of circuit protection, but is generally not used to directly open and close a single motor.
Standard: IEC/EN 60947-3.
Normal operating conditions
Ambient temperature: -5°C~+40°C
Altitude: ≤2000m;
When the ambient air temperature is +40°C, the relative humidity of the air shall not be higher than 50%; a higher relative humidity is allowed at a lower temperature; for example, for the wettest month, the maximum relative humidity averaged shall be 90% while the lowest temperature averaged in that month +20°C, and special measures shall be taken for the condensation occasionally produced due to temperature change.
Pollution degree: 3
The ambient air is not significantly polluted by dust, smoke, corrosive and/or flammable gases, vapours or salt.
