Motor contactor 3RT1 3-pole 5.5kW 24V AC coil

The Siemens 3RT1017-1BB41 is a compact, AC-3 rated power contactor engineered for switching and controlling electrical loads in industrial applications. With a nominal operational current of 12 A and power capacity up to 5.5 kW at 400 V, this three-pole unit integrates a single normally open (NO) auxiliary contact for additional circuit flexibility. Operating on a control voltage of 24 V DC, the device features durable screw terminals that ensure secure connections during installation.

 

This contactor belongs to the S00 size classification, making it ideal for space-constrained installations while maintaining high reliability under heavy-duty conditions. The product's physical dimensions are optimized at 63.50 mm x 50.00 mm x 77.00 mm (L x W x H), with a net weight of approximately 0.265 kg, enabling straightforward integration into existing panel configurations.

 

Designed specifically for use within systems requiring robust performance over extended lifecycles, the product’s construction adheres to stringent manufacturing standards but has reached its end-of-life phase and is succeeded by the advanced SIRIUS model series (e.g., preferred successor type: **3RT2017-1BB41**). For technical or logistical continuity in operations demanding similar specifications, material upgrades can be managed via migration strategies leveraging newer models like the aforementioned successor.

 

Applications include industrial automation platforms where reliable operation is paramount—such as motor starters or switching devices in process control environments—and it aligns with modern engineering practices focused on efficiency and safety compliance within B2B industry sectors such as OEMs and distributed control systems specialists globally.
