It switches loads across a 48-600 V AC supply range with a control voltage of 110-230 V AC, terminated via screw terminals. This relay is designed for mounting on available cooling surfaces — it dissipates heat through its baseplate, so the mounting surface acts as the heatsink. No separate heatsink is included in the package; the panel or chassis metal becomes the thermal path. The packaging dimensions are 104 x 44 x 48 mm, single-piece quantity. ## Integration notes Mounting: the relay bolts directly to a clean, flat metal surface. Thermal compound between baseplate and mounting surface improves heat transfer. The 22.5 mm width matches standard DIN-rail-mount component spacing, but this unit is screw-fixed to the panel, not snapped onto a rail. Control voltage is 110-230 V AC — verify your control transformer or PLC output matches this range. The screw terminals accept standard ring or fork lugs.","metaTitle":"Siemens 3RF3190-1AA26 SIRIUS Solid-State Relay, 90 A, 22.5 m","metaDescription":"Siemens SIRIUS 3RF3190-1AA26 semiconductor relay, 1-pole, 90 A, 48-600 V / 110-230 V AC, screw terminal, 22.5 mm width, mounts on cooling surfaces.
