FCA-325 SERIES Tyco Electronics Mid-Range Military/Aerospace Relays 25 AMPERES, 3PDT HERMETICALLY SEALED ALL WELDED CONSTRUCTION BALANCED FORCE PERMANENT MAGNET DRIVE CONTACTS: SILVER CADMIUM 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 115VAC LIFE (MIN.) 115/200VAC 115/200VAC TYPE OF 28 VDC 3 400HZ CYCLES X 10 400Hz-30 60Hz-30 * LOAD Resistive 25 25 25 2.5 50 Inductive 12 - - 2.5 10 Inductive - 15 15 - 20 Motor 10 10 10 2.0 50 Lamp 5 5 5 1.0 50 * 60 Hz LOADS RATED FOR 10,000 OPERATIONS OVERLOAD CURRENT 50 AMPS DC, 80 AMPS 400HZ RUPTURE CURRENT 60 AMPS DC, 100 AMPS 400HZ CONTACT MAKE BOUNCE 1 MILLISECOND AT NOMINAL VOLTAGE MAX.
