Product details

The Siemens 3RF3150-1AA45 is a SIRIUS 3RF31 series solid-state relay, single-pole, in the 22.5 mm housing width. It switches 50 A continuous at line voltages from 48 to 600 V AC, controlled by a 4-30 V DC input. Screw terminals simplify panel wiring — no special crimp tooling needed for the power or control connections.

At 50 A through a single-pole SSR, thermal management matters: the datasheet derating curve (not reproduced here) governs the actual continuous current at your enclosure ambient.

Frequently asked questions

What are the key electrical ratings?

50 A continuous load current, 48-600 V AC load voltage range, 4-30 V DC control input, and a 1200 V blocking voltage rating.

What compliance documentation is available?

RoHS compliant since 15 January 2024. REACH Article 33 declares lead (CAS 7439-92-1) above 0.1% w/w. No export restrictions under AL/N or ECCN/N.

What is the group code and product group?

Group code R711; product group 3725.

What is the closest alternative in the same family?

Within the SIRIUS 3RF31 family, the closest alternative would differ by load current rating or control voltage range. The 22.5 mm single-pole form factor is shared across the series; verify the specific current and control voltage your application requires.
