Designed and built in

MIL-PRF-6106
The FCAC-150 series relay
is a polarized, single-side
stable design, where the
flux from a permanent mag-
net provides the armature
holding force in the deacti-
vated state, and its flux path
is switched and combined
with the coil flux in the oper-
ated state. This results in
appreciably increased con-
tact pressure in both states
over that of a spring return
non-polar design.
A 1 form C (SPDT) auxiliary
contact set rated 2 amps is
available.

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.
