SERIES FCA-325 Tyco Electronics Mid-Range Military/Aerospace Relays 25 AMPERES, 3PDT VED6 O R P L AP -R-8353 ● HERMETICALLY SEALED ● ALL WELDED CONSTRUCTION ● BALANCED FORCE ● PERMANENT MAGNET DRIVE ● CONTACTS: SILVER CADMIUM QPalified to MIL Qu OXIDE WITH GOLD PLATING ● COILS FOR DC, 50 TO 400Hz AND 400Hz AC ● WEIGHT 2.89 OUNCES MAX. ( 82 GRAMS) 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: FCA-125: 25 AMP SPDT RELAY FCAC-325: 25 AMP 3PST RELAY WITH 2 AMP SPDT AUXILIARY CONTACTS CONTACT RATING-AMPERES Ratings Are Continuous Duty TYPE OF LOAD Resistive Inductive Inductive Motor Lamp LIFE (MIN.)
