Siemens SIRIUS 3RT2026-1AL24 Power Contactor 25A, 11kW, 230V AC Coil, 3-Pole, S0, 2 NO + 2 NC Aux Contacts Original Brand New

Overview

The Siemens SIRIUS 3RT2026-1AL24 is a high-performance 3-pole power contactor from the globally recognized SIRIUS 3RT2 range, designed for switching motors and general loads up to 25 Amps or 11 kW at 400V. This robust contactor features a compact Size S0 footprint, making it ideal for efficient panel designs.

It operates using a standard 230 V AC, 50/60 Hz control voltage and is equipped with a generous configuration of auxiliary contacts: 2 Normally Open (NO) and 2 Normally Closed (NC), provided by a pre-assembled, removable auxiliary switch block. Wiring is secure and straightforward thanks to the classic screw terminal connection for both main and auxiliary circuits.

Function

The Siemens 3RT2026-1AL24 power contactor serves as an essential electromechanical switching device in industrial automation and motor control applications. Its primary function is to safely and reliably switch electrical current to connected loads, primarily three-phase motors. The $230\text{ V AC}$ control coil is energized to close the main $3$-pole contacts, allowing power flow to the $11\text{ kW}$ motor. The integrated $2\text{ NO}+2\text{ NC}$ auxiliary contacts provide crucial feedback and interlocking signals for programmable logic controllers (PLCs), control relays, and other control circuit components.

Benefit

• High Performance in Compact Design: Size S0 offers a balance of high switching capacity ($25\text{ A}$ / $11\text{ kW}$) and space efficiency.
• Reliable and Durable: Part of the trusted Siemens SIRIUS 3RT2 family, providing a mechanical service life of up to 10 million operating cycles.
• Versatile Auxiliary Contacts: Includes $2\text{ NO}+2\text{ NC}$ auxiliary contacts for extensive control and signaling capabilities right out of the box.
• Easy Maintenance: Features a removable auxiliary switch for quick replacement or modification without disturbing the main contactor wiring.
• Global Standard: Approved worldwide and IE3/IE4 ready, ensuring compatibility with modern, high-efficiency motors.
• Secure Connection: Proven screw terminal technology for reliable, high-integrity connections in demanding industrial environments.
