The ring cable lug termination (not a screw clamp or spring cage) means you torque the power wires directly to the relay's terminals — common in panel builds where high ampacity and a vibration-proof connection matter more than quick wire changes. ## Mounting and integration — the thermal path is the heatsink This SSR is designed to be bolted to a metal cooling surface — the backplate of your enclosure or a dedicated heatsink — because the 90 A rating assumes that thermal path exists. The 22.5 mm width matches the SIRIUS 3RF family's compact DIN-rail footprint, so it occupies one standard module slot. For a 90 A relay that's tight on the rail; expect to leave a module gap on either side if the enclosure is sealed or airflow is restricted. The ring lug connection accepts cable lugs sized for the load current — plan your gland plate entry accordingly. RoHS compliant since 15 January 2024. Packaging dimensions are 104 x 44 x 48 mm, unit quantity is one piece.","metaTitle":"Siemens 3RF3190-3AA24 SIRIUS 3RF31 SSR, 90 A, 48-460 VAC","metaDescription":"Siemens 3RF3190-3AA24 SIRIUS 3RF31 solid-state relay, 1-pole, 22.5 mm, 90 A, 48-460 VAC, ring cable lug connection.
