The Series FCB-310 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:

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.
