The Siemens 3RF3125-1BA04 is a 1-pole SIRIUS 3RF31 solid-state relay rated 25 A for 48-460 VAC loads, switched by a 24 VDC control input. Instantaneous switching means the output turns on and off with the control signal — no zero-cross delay, which matters for resistive heater banks or transformer primaries that need fast response.
This is an active, current-production part.
RoHS compliant since 15 January 2024.
RoHS compliance is confirmed since 15 January 2024. REACH Article 33 disclosure identifies lead (CAS 7439-92-1) above 0.1% w/w. Export controls are AL: N / ECCN: N, meaning no special export license is required for standard use.
Rated 25 A continuous load current, switching 48-460 VAC. Control voltage is 24 VDC. The relay is 1-pole, 22.5 mm wide, with screw terminals and instantaneous switching response.
