Bifurcated contact types HC4D

Extremely high contact reliability has
been made possible by adoption of gold-
clad bifurcated contacts for both movable
and stationary contacts.
HC4D type can be used from the dry
circuit 100 µA at 10 V DC to the power
circuit 3 A at 250 V AC resistive load.
Therefore, with HC4D type such a usage
is possible that one contact switches 100
µA and another contact switches 3 A
load. Also Amber sealed types are
available as HC4ED relays.
