Note 1. The above values are initial values. 2. Once the contact is connected to a standard load, it can not be used to connect a smaller load. If so, the contact may result in rough surface, thus losing contact reliability. (1)The protection level is gotten based on test method of (EN60947-5-1). Please make sure its sealing under actual environmental conditions before use. The switch box has dust and oil resistance structure, but it should be used in places without dust, oil and chemicals. Otherwise it may lead to premature wear, damage or malfunction. (2)The durability is for ambient temperature of 5℃ ~ 35℃ and humidity of 40% to 70% RH. For additional details, please contact us. (3)When the ambient temperature is above 35℃, more than 2 circuits 3A 250VAC loads are prohibited. (4)The values will vary with different switching frequency, environmental conditions, reliability level and other factors. Please confirm on the actual load in advance.
