● 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; the contact resistance is low and stable, and contact part can meet IP67 protection level.
● Carrying current 350A continuously at 85ºC.
● Insulation resistance is 1000MΩ( 1000 VDC), and dielectric strength between the coil and contacts is 4kV, which meets the requirements of IEC 60664-1.
