The RA4450HA08 is a single-phase, zero-switching AC solid state relay designed for industrial applications. It operates with a control voltage range of 90 to 280 VAC/DC and is rated for an operational current of 50 AACrms within a voltage range of 42 to 480 VACrms. This relay features a blocking voltage of at least 850 Vp, direct copper bonding technology for thermal efficiency, and provides 4000 VACrms of isolation between the input and output. Its zero-switching characteristic makes it ideal for controlling resistive, inductive, and capacitive loads in environments that may experience high surge conditions.
