The Siemens 3RF3150-1BA06 is a 1-pole SIRIUS 3RF31 solid-state relay in a 22.5 mm housing, rated for 50 A continuous load current across a 48-600 VAC supply range, controlled by a 24 VDC input. It is designed for instantaneous switching and must be mounted on a suitable cooling surface to achieve its full current rating — the housing alone does not dissipate the heat from a 50 A pass-through.
Compliance and regulatory documentation
RoHS compliance is confirmed effective 15 January 2024. The part also carries a REACH Article 33 duty-to-inform declaration for lead (CAS 7439-92-1) above the 0.1% threshold in the current candidate list. Export control classifications are AL: N / ECCN: N, meaning no special export licensing is required for most destinations.
Catalog identification
The Siemens internal group code is R711 and the product group is 3725 — these are used for catalog sorting and cross-reference lookups within Siemens' own systems and by distributors who maintain Siemens line cards.
