Product details

The Siemens 3RF3340-1BA04 is a 1-pole solid-state contactor from the SIRIUS 3RF33 family, rated for AC-15 duty at 20 A at 40 °C ambient. It switches loads on a 48-460 V supply and is controlled by a 24 V DC coil with instantaneous switching. Termination is via screw terminals.

This is a DIN-rail mounted contactor, sized for a standard control panel enclosure. The packaging dimensions of 105 x 27 x 122 mm give you the footprint for layout planning — it takes up about 27 mm of DIN rail width, so factor that into your rail fill and side-to-side clearance for wiring.

Compliance and regulatory notes

RoHS compliant since 15 January 2024.
