It is rated for 50 A continuous load current across a 48-460 V supply range, with a 110-230 V AC control voltage. The 50 A rating is the maximum continuous current the SSR can switch in resistive or moderate inductive loads — for motor or transformer starts, derate per the load's inrush. The 22.5 mm width fits standard DIN-rail panels, but note the ring cable lug termination: this variant is designed for mounting on an external cooling surface (heatsink), not free-air convection. That means the panel builder must provide a suitable thermal path; the relay itself does not include an integrated heatsink. Because it requires an external heatsink, plan for a mounting plate or dedicated cooling surface behind the relay — the packaging dimensions (104 x 44 x 48 mm) give clearance for the lug terminals and wiring. The ring cable lug connection suits permanent wiring in control cabinets where vibration resistance matters more than quick disconnect. ## Sourcing takeaway Active, stocked as a standard product, and specified for the BOM line. The 50 A rating and 48-460 V range cover most three-phase motor and heater loads in 400 V industrial systems. If your line needs a drop-in SSR with external heatsink capability, this is a current-production part with full compliance documentation — submit an RFQ for pricing and lead time.","metaTitle":"Siemens 3RF3150-3AA24 SIRIUS 3RF31 SSR, 50 A, 48-460 V, 22.5","metaDescription":"Siemens 3RF3150-3AA24 solid-state relay, 1-pole, 50 A, 48-460 V, 110-230 V AC coil, ring cable lug, active production.
