● Ceramic brazing sealed technology guarantees no risk of arc leaking and ensures no fire or explosion.
● Filled with gas ( mostly hydrogen) to effectively prevent the oxidation burnt when exposed to electricity; the contact resistance is low and stable, and the parts exposed to electricity can meet IP67 protection level.
● Carrying current 40A continuously at 85°C.
● Insulation resistance is 1000MΩ(1000 VDC), and dielectric strength between the coil and contacts is 4kV, which meets the requirements of IEC 60664-1.
● No specific polarity requirements for the connection
