Siemens 3RT2017-2MB41-0KT0 SIRIUS Power Contactor 12A, 5.5kW, 24V DC, 1 NO, Spring-Loaded Original Brand New

Overview

The Siemens 3RT2017-2MB41-0KT0 SIRIUS Power Contactor is a high-performance and reliable solution for a wide range of industrial control and automation applications. This compact and robust 3-pole contactor is designed for AC-3e/AC-3 switching applications, handling a rated operational current of up to 12 A and a power output of 5.5 kW at 400 V. Its 24 V DC control voltage, with a wide operating range of 0.85 to 1.85 times the control supply voltage (Uc​), ensures stable and reliable operation in diverse power supply conditions.

The integrated 1 NO auxiliary contact provides additional control and feedback capabilities, while the innovative spring-loaded terminals offer fast, secure, and vibration-proof connections, significantly reducing installation and maintenance time. With its compact S00 frame size, this contactor is ideal for space-constrained installations.

Key Features & Benefit

• High Performance: Rated for 12 A (AC-3e/AC-3) and 5.5 kW at 400 V, making it suitable for motor control and general switching tasks.
• Reliable DC Operation: Operates on a 24 V DC control voltage with an extended range (0.85−1.85×Uc​) for consistent performance even with voltage fluctuations.
• Integrated Auxiliary Contact: Features a built-in 1 NO (Normally Open) auxiliary contact for feedback, interlocking, or signaling purposes.
• Fast & Secure Connections: Spring-loaded terminals provide a strong, gas-tight connection that is resistant to vibration, ensuring long-term reliability and reducing the need for retightening. This technology saves up to 50% of wiring time compared to screw terminals.
• Space-Saving Design: The compact S00 frame size allows for high-density installations in control cabinets and panels.
• Durable and Long-Lasting: Part of the trusted Siemens SIRIUS series, known for its robust construction and high electrical and mechanical endurance.
• Simplified Installation: "No auxiliary switch can be added" indicates a fixed, streamlined configuration, simplifying selection and installation.
