3RT1017-2BB41 - Siemens Contactor

If you’re maintaining or servicing an existing motor control system, you don’t need guesswork—you need a contactor that fits, performs, and installs without headaches. The Siemens 3RT1017-2BB41 power contactor delivers exactly that. Designed for AC-3 applications up to 12 amps, this unit handles motor loads up to 5.5 kW at 400V, making it a dependable choice for a wide range of industrial control setups.

Its compact S00 frame size makes it easy to integrate into tight panels, while the 24V DC coil aligns with standard low-voltage control circuits found in many systems. Installation is straightforward thanks to spring-type terminals, which provide a firm, vibration-resistant connection without the need for constant retightening. The built-in 1 normally open (NO) auxiliary contact adds flexibility for signaling or interlocking, helping you keep your control logic clean and efficient.

This contactor is built with durability in mind—designed to handle repeated switching cycles and keep systems running smoothly over time. Whether you’re replacing an existing unit or maintaining legacy equipment, the 3RT1017-2BB41 offers the right combination of fit, function, and reliability to keep your operation moving.
