Siemens 3RT2026-2AN24 Contactor, SIRIUS S0, 25A, 11kW, 2NO+2NC, Spring Original Brand New

Overview

The Siemens 3RT2026-2AN24 is a high-performance, 3-pole SIRIUS 3RT20 power contactor designed for reliable switching of motors and other high-current loads up to $25\text{ A}$ (AC-3e/AC-3) or $11\text{ kW}$ at $400\text{ V}$. Part of the compact Size S0 range, this industrial-grade contactor features a $220\text{ V}$ AC, $50/60\text{ Hz}$ control voltage for easy integration into standard control circuits. It is equipped with quick and secure spring-loaded terminals and includes a versatile configuration of 2 NO (Normally Open) + 2 NC (Normally Closed) auxiliary contacts for signaling and interlocking, which are conveniently removable.

Benefit

1. Time-Saving Installation: The innovative spring-loaded terminal technology allows for fast, tool-free wiring, ensuring reliable, vibration-proof connections and significantly reducing installation and maintenance time compared to traditional screw terminals.
2. Compact, Space-Saving Design: As a Size S0 contactor, it offers a high power-to-size ratio, maximizing space efficiency within control cabinets and industrial enclosures.
3. High Reliability & Safety: Built with Siemens SIRIUS quality, the 3RT20 series is engineered for high mechanical and electrical endurance, ensuring a long service life and reliable motor switching in demanding industrial environments.
4. Flexible Control Integration: The integrated and removable auxiliary switch block ($2\text{ NO}+2\text{ NC}$) provides extensive options for interlocking, signaling, and sequence control without needing external add-on blocks.
5. Global Compliance: Conforming to major international standards (e.g., IEC), this product is suitable for use in machinery and systems worldwide.

Function

The 3RT2026-2AN24 power contactor is primarily used for:

• Switching 3-Phase Motors: Ideal for starting and stopping electric motors up to $11\text{ kW}$ in applications like pumps, fans, conveyors, and machine tools.
• Controlling Electrical Loads: Suitable for switching resistive and highly inductive loads such as heating elements, lighting systems, and capacitor banks.
• System Integration: The $2\text{ NO}+2\text{ NC}$ auxiliary contacts are perfect for feedback to a PLC (Programmable Logic Controller) or control system for status monitoring and safety interlocks.
• Automation: Essential component in control panels for motor starter circuits (direct on-line starters, reversing starters).
