FCA-325 Series, 25 Amperes, 3PDT
The Series FCA-325 relay
is a polarized single-side
stable design, where the
flux 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
spring return nonpolar
design. We also
manufacture other versions
of this relay:

Terminal Wiring
NOTE: Polarity must be observed with DC coil supply.
Relay is polarized with a permanent magnet and will not
operate or be damaged by reverse polarity.
Diodes used in transient suppression and in AC rectifier
circuits have peak inverse voltage rating of 600 VDC
minimum. Zener diodes have a minimum rating of 1 watt.
Terminal designations are for reference only and do not
appear on the header.
