Product Positioning

The 3RT1017-1AF02 is a small three-pole contactor in the Siemens SIRIUS 3RT10 series with an S00 frame. It is designed for 110V AC control circuits and is commonly found in transformer step-down power supplies or special control power supply equipment. The AC-3 rated 12A can directly switch a 5.5kW three-phase motor at 400V. It is compact yet has industrial-grade reliability and has a built-in normally closed auxiliary contact for easy construction of interlocking protection circuits.

Core Product Advantages and Features

S00 Small Frame

Its compact size makes it suitable for control box configurations with limited space, and it can be directly mounted on a 35mm standard DIN rail.

12A/5.5kW switching capacity

The AC-3 has a rated current of 12A and can stably switch a 5.5kW three-phase motor load at 400V.

110V AC coil

The coil voltage is 110V, and it is universally compatible with 50/60Hz, making it easy to connect to existing special control voltage systems.

1 set of normally closed auxiliary contacts

It has a built-in 1NC auxiliary contact, which can be used for interlocking loops or status monitoring feedback.

Screw terminal design

Both the main and auxiliary circuits use screw terminals, making wiring, construction, maintenance, and repair quite convenient.

High mechanical life

Typical mechanical life reaches 30 million operations, with stable and reliable long-term operation.
