Product details

The Siemens 3RF3340-1BA06 is a 1-pole SIRIUS 3RF33 solid-state contactor rated for AC-15 duty at 20 A at 40 °C, with a load voltage range of 48-600 V and a 24 V DC control coil. AC-15 is the switching category for electromagnetic loads — solenoids, contactor coils, and clutches — where the inrush can be several times the holding current. The 20 A AC-15 rating means it handles that inrush without welding or degradation, unlike a resistive-load rating that would fail under the same surge.

Where this contactor fits in a control system

Its screw terminals accept the load and control wiring directly — no additional socket or base required.

Frequently asked questions

What is the group code and product group for this item?

The group code is R711 and the product group is 3725. These are Siemens internal classification codes used for catalog organization and cross-referencing.

What load types is the AC-15 rating suitable for?

AC-15 is the switching category for electromagnetic loads — contactor coils, solenoid valves, and clutches. The 20 A rating at 40 °C means it handles the high inrush current typical of these loads without damage, unlike a resistive-load (AC-1) rated device.
