That 90 A figure is the AC-1 resistive rating — the current it can switch continuously with resistive loads like heaters or ovens. For motor or inductive loads, the actual switching capacity will be lower; the 90 A number gives you the headroom for inrush if you're driving a transformer or incandescent lamp bank. The 22.5 mm housing width is standard for DIN-rail mounting, so it fits alongside contactors and overloads in a typical control panel without eating extra rail space. ## Control voltage and termination Control input accepts 24-230 V AC/DC, with a 24 V DC nominal pick-up. That wide control range means a single relay works across mixed-voltage panels — 24 V DC for PLC-driven outputs or 230 V AC for direct line-voltage switching. ## Mounting and thermal management This relay is designed for mounting on available cooling surfaces — the 90 A rating assumes the baseplate is bolted to a metal panel or heatsink. The 104 x 44 x 48 mm package dimensions fit standard DIN-rail enclosures; plan for airflow around the relay if it's in a sealed cabinet with other heat-generating components.","metaTitle":"Siemens 3RF3190-2AA02 SIRIUS 3RF31 SSR, 90 A, 22.5 mm","metaDescription":"Siemens SIRIUS 3RF3190-2AA02 solid-state relay, 1-pole, 90 A, 24-230 V / 24 V DC control, spring-loaded terminals.
