The Siemens 3RF3190-3AA22 is a 1-pole solid-state relay from the SIRIUS 3RF31 family, in the 22.5 mm housing width. It is rated for 90 A continuous current at 24-230 V AC control voltage, with a 110-230 V AC load circuit. The connection uses ring cable lugs, and the relay is designed for mounting on an available cooling surface — no built-in heatsink, so the panel builder must provide adequate thermal management for the 90 A load. For motor or resistive heating loads at 230 V AC, this relay switches up to that current level.

Product details
Frequently asked questions
What compliance documentation is available for this relay?
RoHS compliant since 15 January 2024. REACH Article 33 applies due to lead content above 0.1% by weight. No export restrictions (AL: N, ECCN: N).
What group code and product group does this part belong to?
Group Code R711, Product Group 3725.
What is the closest alternative in the same family?
Within the SIRIUS 3RF31 series, the closest peer is the 3RF3190-3AA22 itself — there is no pin-compatible alternative listed as a direct replacement. For a lower current rating, the 3RF3 family includes 22.5 mm variants at 50 A and 75 A, but they differ in the ring lug connection and cooling requirements.
