Product details

Solid-state relay for motor and heater switching

The Siemens 3RF3025-1AA45 is a 1-pole solid-state relay from the SIRIUS 3RF30 family, in the 45 mm width housing. It switches 25 A continuous at 48-600 VAC load voltage, controlled by a 4-30 VDC input. The 1200 V blocking voltage gives headroom for transient spikes common on motor and heater circuits in crusher and conveyor panels.

The 45 mm width snaps onto standard DIN rail inside an enclosure. Screw terminals accept the load and control wiring — no special tooling needed for the 25 A circuit. The 1200 V blocking voltage means it handles the back-EMF from inductive loads without external snubbers in most cases, though a varistor across the load is still good practice in high-vibration environments where a loose terminal could cause arcing.

Frequently asked questions

What compliance documentation is available for this relay?

RoHS compliance is confirmed from 15-01-24. REACH Article 33 disclosure identifies lead (CAS 7439-92-1) above 0.1% w/w. These documents support regulatory audits for industrial installations.

What is the group code and product group for this part?

The group code is R711 and the product group is 3725. These are Siemens internal classification codes used for catalog sorting and replacement cross-referencing.

What is the closest alternative within the SIRIUS 3RF30 family?

Within the same 1-pole 45 mm footprint, the 3RF3025-1AA45 is the 25 A variant. The family also includes 20 A and 32 A versions with the same control voltage range and terminal layout, so a swap requires checking the load current against the BOM rating.
