The Siemens 3RF3350-1BA06 is a 1-pole solid-state contactor from the SIRIUS 3RF33 family, rated for AC-15 duty at 25 A at 40 °C ambient. It switches loads between 48 and 600 V AC, controlled by a 24 V DC coil with instantaneous switching. Termination is via screw terminals. AC-15 is the switching category for electromagnetic loads — solenoids, contactor coils, and similar inductive control circuits. The 25 A rating at 40 °C means it can handle that current continuously in a panel at typical ambient temperatures without derating.
For BOM freeze or line-down sourcing, the active status means no last-time-buy pressure.
Integration notes
Packaged as a single piece, dimensions 105 x 50 x 125 mm. The screw terminals accept standard control wiring. The 24 V DC coil is common for PLC-driven panels; verify the control supply is clean and within tolerance to avoid nuisance dropout.
