Siemens 3RT2 Contactor, 24V dc Coil, 3-Pole, 12 A, 5.5 kW, 3 NO, 400V ac 3RT2017-1BB41

Siemens 3RT2017-1BB41 Contactor featuring a 24V dc coil, 3 poles, and a 12 A current rating is designed for industrial motor control applications. Part of the Siemens SIRIUS Innovation 3RT2 Series, this contactor safely controls and protects motors by energizing the three normally open (NO) contacts, enabling reliable motor start-up.

With an auxiliary contact configured as 1 NO, the device provides enhanced control by triggering a power cutoff during surge currents to protect connected motors from damage. Its surge voltage rating of 6kV makes it robust against sudden electrical spikes, improving safety in demanding industrial settings.

The tough thermoplastic housing is impact-resistant to withstand harsh manufacturing and construction environments. Compact dimensions (57.5mm length, 45mm width, 73mm depth) allow for space-efficient installation inside control panels, mounted easily on DIN rails without need for tools.

Operational temperature ranges from -25°C to +60°C, accommodating a variety of ambient conditions commonly found in industrial, manufacturing, HVAC, and compressor applications. The contactor is rated for a power load of 5.5 kW at 400V ac and supports an operational current of up to 22A, ideal for heavy-duty motor protection and control.

Coil voltage: 24V dc for precise activation and control. Three fully rated poles with 3 normally open contacts for motor circuit connections. Single auxiliary contact configured as 1 NO for signaling or interlocking purposes.

Mounts on standard DIN rail for convenience and flexibility. Robust thermoplastic housing ensures durability in industrial use. Rated power of 5.5 kW and current of 12 A meets requirements for medium power motors. Can handle operational current up to 22A, allowing for surge tolerance.

Mechanical life expectancy of 30 million operations ensures longevity and reliability. Operating temperature range from -25°C to +60°C suitable for varied environments. Supports industrial automation, motor control, HVAC systems, and compressor protection.

This Siemens contactor is manufactured in Germany, adhering to high manufacturing standards and certifications such as EAC compliance. Its low carbon manufacture aligns with sustainable industrial practices.
