AC-15 is the switching category for electromagnetic loads — solenoids, contactor coils, clutches, brakes — where the inrush can hit several times the holding current. The 25 A figure is the thermal continuous current under those conditions, not a resistive-heater rating. If your load is a motor or resistive heater, the AC-15 curve isn't the right one; this part is sized for inductive control circuits. ## Control voltage flexibility The control input accepts 24-230 V AC or 24 V DC, covering both standard industrial control voltages and mixed-voltage panels. No separate coil variant to order — one part number handles the range. The DC side is 24 V nominal, so verify your control transformer or power supply sits within that band; the AC side stretches to 230 V line, which is useful for direct connection to a 230 V control circuit without an interposing relay. Screw terminals, so expect a screwdriver for termination — no spring-cage tool needed. Packaging dimensions 105 x 50 x 125 mm, which fits a standard DIN-rail footprint. Single-pole form factor means one phase switched; for three-phase loads you'll need three units or a three-pole variant. The 40 °C ambient derating is already baked into the 25 A figure — no additional derate calculation at that temperature.","metaTitle":"Siemens 3RF3350-1BA02 SIRIUS 3RF33 Solid-State Contactor, 1-","metaDescription":"Siemens 3RF3350-1BA02 SIRIUS 3RF33 solid-state contactor, 1-pole, rated 25 A AC-15 at 40 °C. 24-230 V AC / 24 V DC control.
