AC Leakage circuit breaker

• Voltage: The voltage continuously applied between the SPD terminals does not exceed the maximum continuous working voltage Uc 

• The altitude should not exceed 2000m 

• Ambient air chlorine temperature: normal range -5°C~+40°C, extreme range -40°C~+85°C. 

• Relative humidity: should be between 30% and 90% at room temperature 

• The SPD adopts 35mm standard guide rail to install the product in the distribution cabinet or box of the distribution box. 

• The connecting line should be as short as possible, and the total length should be less than 0.5m
