Product details

Siemens' SIRIUS 3RF33 line includes this 1-pole solid-state contactor, the 3RF3350-1AA04. It switches resistive loads up to 50 A at 40 °C across 48–460 V AC, with a 24 V DC control signal coming in through screw terminals. You'll find these in control panels for heating elements, lighting banks, or any place you need silent cycling without the mechanical wear. The compact dimensions (105 x 50 x 125 mm) save rail space and keep the panel layout tight.

Rated AC-1 at 50 A / 40 °C for resistive loads. Control side requires a stable 24 V DC supply via screw terminals.

Frequently asked questions

What is the maximum continuous load current at 40 °C ambient?

50 A under AC-1 conditions (resistive load) at 40 °C ambient.

What are the packaging dimensions of the 3RF3350-1AA04?

105 mm x 50 mm x 125 mm (L x W x H).

Is the control voltage strictly 24 V DC only, or does it accept a range?

The specification states 24 V DC. No range is provided, so the control supply should be regulated at 24 V DC.
