Siemens 3RT2026-2KB40 Power Contactor 25A, 11kW, 24V DC, Spring-Loaded Terminals Original Brand New

Overview

The Siemens SIRIUS 3RT2026-2KB40 is a high-performance power contactor designed for reliable switching of motors and other electrical loads up to 11 kW (at 400 V). This compact and efficient device, part of the SIRIUS modular system, is engineered for applications where space and reliability are critical. With a rated operational current of 25A for AC-3e/AC-3, it’s a perfect fit for a wide range of industrial control systems. The integrated 24V DC coil, with a wide control range of 0.7-1.25*Uc, and a plugged-in varistor ensures seamless operation with PLC outputs, providing robust protection against voltage spikes. The spring-loaded terminals make installation quick and secure, saving you time and effort. Its S0 frame size makes it highly versatile.

Key Benefit

• Optimized for PLC Outputs: The 24V DC coil and wide voltage range make it ideal for direct connection to PLC outputs, simplifying your control design.
• Reliable Surge Protection: An integrated varistor protects the coil from overvoltage surges, extending the contactor’s lifespan and ensuring stable performance.
• Fast & Secure Wiring: Spring-loaded terminals eliminate the need for specialized tools, reducing wiring time and providing a vibration-resistant connection.
• Compact & Space-Saving: The small S0 frame size allows for high-density installations in control cabinets where space is at a premium.
• Durable & Long-Lasting: Built to the highest standards, this contactor offers a long electrical and mechanical life, reducing maintenance and replacement costs.
