FCA-125 Series, 25 Amperes, SPDT
The Series FCA-125 relay
is a polarized single-side
stable design, where the
f
lux from a permanent
magnet provides the
armature holding force in
the deactivated state, and
its flux path is switched and
combined with the coil flux
in the operated state.
This results in appreciably
increased contact pressure
in both states over that of a
s
pring return nonpolar
design. We also
manufacture other versions
of this relay:
FCA-325 — 25 Ampere
