Siemens 3RT2026-2AF00 Power Contactor, AC-3e/AC-3, 25A, 11kW, 110V AC, Spring-Loaded Terminal, Size S0 Original Brand New

Overview

The Siemens 3RT2026-2AF00 Power Contactor is a robust and reliable 3-pole device from the SIRIUS 3RT2 series, designed for the highly efficient switching of motors and other resistive loads. Engineered for performance and longevity, this Size S0 contactor features a 110 V AC, 50 Hz control coil and is rated for a maximum operating current of 25 A and a power output of 11 kW at 400 V (AC-3e/AC-3).

A key feature is the modern spring-loaded terminal connection technology, which ensures fast, vibration-proof, and maintenance-free wiring, significantly reducing installation time and increasing operational security. The unit includes integrated auxiliary contacts: 1 NO (Normally Open) + 1 NC (Normally Closed), providing essential feedback and control capabilities for complex industrial automation systems.

Benefits and Advantages

• Quick Installation: The innovative spring-loaded terminal system allows for rapid, tool-free wiring, slashing setup time and minimizing labor costs.
• Vibration-Proof Connection: Ensures maximum contact reliability, even in high-vibration environments, guaranteeing consistent performance and safety.
• Compact Design (Size S0): Optimized dimensions save valuable space within the control cabinet, facilitating higher component density.

Function and Application

The 3RT2026-2AF00 contactor is primarily used in industrial applications for reliably switching 3-phase AC motors. Its robust design is suitable for:

• Starting and stopping electric motors (e.g., pumps, fans, conveyors).
• Switching resistive loads (e.g., heating elements).
• Integration into complex machine control systems, motor starters, and load feeders.
