Features
• 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 300Acontinuouslyat 85° C.
• Insulation resistance is 1000^3 ( 1000VDC), and dielectric
strength between the coil and contacts is 4KV, which meets the
requirements of IEC 60664-1.
• Coil with energy-saving devices.
