Siemens 3RT2017-2LB41-1AA0 SIRIUS Power Contactor AC-3e/AC-3, 12A, 5.5kW, 24V DC, Spring-Loaded Terminal, S00 Frame Original Brand New

Overview

The Siemens 3RT2017-2LB41-1AA0 is a highly efficient and compact power contactor from the SIRIUS line, specifically designed for industrial motor control applications. This 3-pole contactor is engineered for AC-3e/AC-3 operation, making it suitable for a wide range of tasks, including switching motors and other resistive loads up to 12 A or 5.5 kW at 400 V. Its compact S00 frame size and upright mounting position make it an excellent choice for applications where space is at a premium.

Benefit

• Space-Saving Design: The compact S00 frame size allows for high-density installations in control cabinets, maximizing available space.
• Reliable Operation: The integrated varistor protects the contactor and connected equipment from voltage spikes, ensuring a long service life and reliable performance.
• Quick and Secure Wiring: Spring-loaded terminals provide fast, vibration-proof, and maintenance-free connections, reducing installation time and costs.
• Energy Efficiency: The 24V DC control voltage with a wide operating range of 0.7-1.25*Uc provides reliable switching while minimizing power consumption in the control circuit.
• Enhanced Functionality: The built-in 1 NO (normally open) auxiliary contact provides additional signaling and control options for interlocking or status indication.

Function

• Motor Switching: Effectively switches 3-phase AC motors with a rated current of 12 A and a power rating of 5.5 kW.
• Integrated Protection: The integrated varistor absorbs transient overvoltages, safeguarding the coil and the entire system from electrical stress.
• Auxiliary Signaling: The 1 NO auxiliary contact can be used to signal the ON state of the main circuit to a PLC or another control device.
• Reliable Control: The wide control voltage range ensures stable operation even with fluctuations in the 24V DC supply.
