HONGFA High voltage DC relay,Carrying current 400A,Load voltage 450VDC 750VDC HFE82V-400M

Product Information

Outline Dimensions:95.8 x 49.0 x 93mm

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 400A continuously at 85°C.

● Insulation resistance is 1000MΩ(1000 VDC), and dielectric

strength between the coil and contacts is 3kV, which meets

the requirements of IEC 60664-1.
