Basic Info.
Model NO.
HFE18V-40/750-24-HL5
Protective Characteristics
Open Relay
Mechanical Endurance
2 X 105 OPS
Specification
67 x 32.6 x 47 mm
Product Description
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 40A continuously at 85° C.
• Insulation resistance is 100Om5( 1000VDC), 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
