Siemens 3RT2025-1NF30 SIRIUS Power Contactor 17A, 7.5kW, 95-130V AC/DC, S0 Size Original Brand New

Overview

The Siemens 3RT2025-1NF30 is a high-performance SIRIUS series power contactor engineered for reliable and efficient switching of electrical loads. This 3-pole contactor, part of the trusted Siemens portfolio, is designed to meet the demands of modern industrial applications. With a robust build and a compact S0 size, it’s the ideal component for motor control, switching resistive loads, and other power-intensive tasks.

The integrated varistor provides superior surge protection, ensuring longevity and stable performance of the coil. The inclusion of one normally open (NO) and one normally closed (NC) auxiliary contact offers added flexibility for control and signaling circuits.

Key Features & Benefit

• High-Rated Performance: The contactor is rated for a current of 17 A and a power of 7.5 kW at 400 V (AC-3e/AC-3), making it suitable for a wide range of motor and load control applications.
• Versatile AC/DC Coil: The wide operating range of the coil (95-130 V AC/DC) provides flexibility and simplifies inventory by reducing the need for separate AC and DC versions.
• Integrated Varistor: This built-in feature protects the coil from damaging voltage spikes, enhancing the contactor’s lifespan and reliability.
• Space-Saving Design: The compact S0 size allows for efficient use of space within control cabinets, making it perfect for installations where panel real estate is a concern.
• Dual Auxiliary Contacts: The inclusion of 1 NO + 1 NC auxiliary contacts offers easy integration into complex control circuits, enabling status monitoring and interlocking functions.
• Secure Screw Terminals: The screw terminal connection ensures a strong, reliable, and easy-to-install electrical connection, minimizing downtime during installation and maintenance.
• Durable and Reliable: As part of the Siemens SIRIUS family, this contactor is built to the highest quality standards, guaranteeing long-term performance and durability in demanding industrial environments.

Function

The Siemens 3RT2025-1NF30 power contactor serves as an electro-mechanical switch for controlling electrical circuits. It is primarily used for switching motors, but can also be applied to control lighting, heating, and other power loads.

When the coil is energized by the 95-130 V AC/DC control voltage, the main contacts close, allowing power to flow to the connected load. The auxiliary contacts simultaneously change their state, providing feedback for the control system. The integrated varistor protects the coil from overvoltage, ensuring reliable operation.
