**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 ——i design creates a reliable alternative to similar solder sealed relays in the market. j 4 =
