400 Amp Disconnect Single Phase Outdoor

400 amp outdoor low-voltage disconnect switches are suitable for 0.5kV, 50Hz distribution lines. Outdoor disconnectors serve as protection and overload protection for the low-voltage side of transformers. Under certain conditions, they can be used for no-load transformers, no-load lines and rated working currents.Complies with standards: GB/T14048.3, IEC 60947-3.

1. During electrical equipment maintenance, an electrical separation and a clearly visible disconnect point are required to ensure the safety of maintenance personnel.

2. Isolators must not be operated under load: they cannot operate with rated or high loads, and cannot open or close load currents or short-circuit currents. However, those with arc extinguishing chambers can operate with light loads and no-load lines.

3. During normal power-on operation, close the isolator first, then the circuit breaker or load switch. During power-off operation, open the circuit breaker or load switch first, then the isolator.

4. When selecting an isolator, as with other electrical equipment, its rated voltage, rated current, dynamic stability current, thermal stability current, etc. must meet the requirements of the application.

• Altitude not exceeding 2000 meters.
• Ambient temperature not exceeding +40°C and not below -25°C.
• Relative humidity not exceeding 85% (relative to +20±5°C).
• Store in a well-ventilated, dry environment free from combustion and explosion hazards, severe vibration and shock, and chemicals that are severely corrosive to metal and insulating materials.
