Reference: A maximum current of 0.15 A can
be
switched at 125
VDC
(cosφ = 1).
Maximum current of 0.1 A can
be
switched if L/R is 7 ms. In
both
cases, a
life of 100,000 operations can
be
expected.
Note:
1. The H3CA Series has
been
tested for the following: impulse
voltages,
noise
(via noise simulator, for L loads, and for relay oscillation), and resistance to
static electricity.
2. Minimum applicable load (P reference
