Siemens 3RT2025-2AV00 SIRIUS Power Contactor, 17A, 7.5kW, 400V AC, Spring-Loaded Terminal, Size S0 Original Brand New

Overview: The SIRIUS 3RT2025-2AV00 Power Contactor

The Siemens 3RT2025-2AV00 is a high-performance, 3-pole power contactor from the trusted SIRIUS 3RT2 family, designed for switching motors and general resistive loads up to 7.5 kW at 400 V (AC-3 rating). This reliable and compact Size S0 contactor is engineered for efficiency and high contact reliability, making it an essential component for motor control and industrial automation systems.

A key feature of the 3RT2025-2AV00 is its use of spring-loaded terminals, which provide a fast, maintenance-free, and vibration-proof connection, drastically reducing wiring time and ensuring secure operation in demanding industrial environments.

Key Benefit

1. Fast & Reliable Wiring: The spring-loaded terminal connections enable rapid and secure installation without the need for periodic retightening, ensuring a vibration-proof connection and significantly reducing maintenance costs.
2. Compact Design: As a Size S0 contactor, it offers high switching capacity in a small footprint, saving valuable panel space within control cabinets.
3. High Compatibility (SIRIUS Modular System): It is part of the comprehensive SIRIUS modular system, ensuring optimal, tested, and coordinated integration with other components like overload relays and circuit breakers for a complete load feeder solution.
4. Global Use: Approved to international standards (e.g., IEC and UL/CSA), making it suitable for use in equipment destined for worldwide markets.
5. Energy Efficiency: The contactor is IE3/IE4 ready, supporting modern, high-efficiency motor applications and contributing to reduced energy consumption.

Function

The Siemens 3RT2025-2AV00 Power Contactor functions as an electrically controlled switch used for remotely controlling power in an electrical circuit. It is primarily used for switching three-phase AC motors on and off. The integrated auxiliary contacts (1 NO + 1 NC) provide feedback and interlocking signals for control circuits, confirming the contactor’s status to a PLC or control system. Its $400\text{ V AC coil}$ ensures reliable actuation for control systems operating at this standard European industrial voltage.
