Siemens SIRIUS 3RT2017-1FB41 Power Contactor 12A, 5.5kW, 24V DC Coil, 3-Pole, Size S00 Original Brand New

Overview: Reliable Motor Switching with Siemens 3RT2017-1FB41

The Siemens SIRIUS 3RT2017-1FB41 is a high-performance, compact 3-pole power contactor designed for the reliable switching of motors and resistive loads in industrial automation applications. As part of the globally recognized SIRIUS modular system, this device ensures consistent operation and features a small footprint (Size S00), making it ideal for space-constrained cabinets.

This specific model is engineered for DC operation, featuring a 24 V DC control voltage coil with an integrated diode to suppress opening surges, protecting your control system components. It has a rated operational current of 12 A and a motor power rating of 5.5 kW at 400 V (AC-3e/AC-3). The main and auxiliary circuits utilize robust screw terminals for a secure and dependable connection.

Benefit

1. Compact, Space-Saving Design: The Size S00 form factor minimizes panel space requirements, simplifying cabinet design and reducing overall control system footprint.
2. Enhanced Coil Protection: The integrated diode within the 24V DC coil provides essential surge suppression, increasing the lifespan of the contactor and protecting sensitive PLC and control circuit components.
3. High Reliability: Engineered as part of the SIRIUS modular system, it offers a high degree of contact reliability and mechanical endurance for demanding industrial environments.
4. Simple and Secure Wiring: Robust screw terminals on both the main and auxiliary circuits ensure a quick, easy, and vibration-proof installation.
5. Motor and Load Flexibility: Ideal for AC-3 (motor starting) and AC-1 (resistive load) switching applications.

Function

The Siemens 3RT2017-1FB41 contactor is primarily used to switch on and off electric motors or resistive loads. When the 24 V DC coil is energized, the 3-pole main contacts close, connecting the load (e.g., a motor) to the 400 V supply. The integrated 1 NO auxiliary contact provides instant signaling feedback to the control system or can be used for interlocking functions in complex circuits.

Application

• Motor control for pumps, fans, and compressors.
• Direct-on-Line (DOL) starters.
• Control of heating systems and lighting circuits (AC-1 loads).
• Integration into automated industrial machinery and production lines.
