· 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 300A continuously at 85°C.
· Insulation resistance is 1000m?( 1000VDC), and dielectric
strength between the coil and contacts is 4KV, which meets the
requirements of IEC 60664-1.
· Coil with energy-saving devices.
