Operating Steps
Power-On Operation: First close the isolating switch, then close the circuit breaker or load switch.
Power-Off Operation: First open the circuit breaker or load switch, then open the isolating switch.
Model Selection
When selecting an isolating switch, ensure that its rated voltage, rated current, dynamic stability current, and thermal stability current meet the requirements of the application. The primary role of the isolating switch is to disconnect circuits with no load current, allowing for safe maintenance. Before operating the isolating switch, ensure that the circuit breaker has disconnected the circuit.
Use environmental conditions
1. The upper limit of ambient temperature +40°C, the lower limit -10°C, Note: Allow storage and transportation at-25°C
2. Altitude not more than 1000m
3. Relative humidity: daily average is not more than 95%, monthly average is not more than 90%
4. Water vapor pressure: the daily average is not more than 2.2x 10-3Mpa, the monthly average is not more than1.8 x 10-3Mpa
5. The surrounding air should be free from corrosive or combustible gases, water vapor and other obvious pollution.
