FC-325-CW4

CII FC-325 SERIES RELAYS HERMETICALLY SEALED, NON-LATCHING 25-AMP RELAYS FEATURING DOUBLE MAKE/BREAK CONTACT DESIGN, ALL WELDED ENCLOSURE, AND MS27418 QUALIFICATION. COMMERICAL VERSIONS WITH 2A SPDT AUXILIARY CONTACT ALSO AVAILABLE. AEROSPACE, DEFENSE & MARINE /// FC-325 SERIES RELAYS CII FC-325 Series Relays Compact, Hermetically Sealed, Non-Latching Relays FC-325 Series relays from TE Connectivity (TE) are hermetically sealed devices designed for harsh inductive, motor, and lamp load applications in aerospace, defense, and marine markets. Configured as a 3PST/NO (DM), the double make/break contact design of the CII FC-325 Series relays offer higher capability than comparable relays in the market. It shares the load across two contact sets, resulting in less wear and tear on the relay. This provides stable performance and extends the relay’s life. The relay’s all welded design creates a reliable alternative to similar solder sealed relays in the market. CII FC-325 Series Relays MECHANICAL/ENVIRONMENTAL • Temperature Range: -70°C to +125°C • Altitude: 80,000 feet • Sinusoidal Vibration: 10 g/5 to 1000 Hz • Shock: 50 g/11 ms ELECTRICAL • Dielectric Strength at Sea Level: Coil to Case: 1250 Vrms All Other Points: 1500 Vrms RUGGED • Hermetically sealed • Corrosion protected metal can •A  ll welded construction.
