Siemens 3RT7026-1AG25 Contactor 25A, 11kW, 110V AC Coil, Screw Terminals, Size S0 Original Brand New

Overview: The Siemens 3RT7026-1AG25 Contactor

The Siemens 3RT7026-1AG25 is a high-performance power contactor designed for industrial control applications. As part of the SIRIUS series, it’s engineered for reliability, durability, and seamless integration into automation systems. This 3-pole contactor is rated for AC-3 duty at 25A and 11kW, making it ideal for switching standard asynchronous motors up to 400V. Its compact Size S0 design saves valuable space in control cabinets, while the integrated 1NO (normally open) and 1NC (normally closed) auxiliary contacts provide essential feedback and control signals. The robust screw terminals ensure a secure and reliable electrical connection, simplifying installation and maintenance.

Key Benefit

• Exceptional Reliability: Built with Siemens’ renowned quality, this contactor provides long-term, stable performance, minimizing downtime and maintenance costs.
• Space-Saving Design: The compact Size S0 footprint allows for higher component density in control panels, optimizing cabinet layout.
