Benefits & Features

1. High Reliability & Longevity: Part of the industry-leading Siemens SIRIUS family, ensuring a long mechanical and electrical service life for demanding industrial environments.
2. Wide Voltage Compatibility (UC Coil): The 95-130 V AC/DC coil (Universal Control Voltage) offers flexibility, allowing the contactor to be used in both AC and DC control circuits within the specified range, simplifying inventory and engineering.
3. Integrated Surge Suppression: Includes a built-in varistor, protecting the control coil and the entire control circuit from voltage spikes, which significantly increases system reliability.
4. Space-Saving Design (Size S0): Compact footprint allows for efficient use of space within control cabinets, making it ideal for modern, high-density installations.
5. Easy Installation & Wiring: Features robust screw terminals for secure and reliable wiring connections, suitable for standard industrial practices.
6. Ready for Motor Control: Perfectly suited for standard motor starting applications (AC-3e/AC-3) as well as general-purpose load switching.

Function

The Siemens 3RT2024-1NF30 Power Contactor acts as an electrically operated switch for switching a main power circuit. It is primarily used for:

• Switching 3-Phase Motors: Start and stop control for motors up to 5.5 kW.
• Switching Resistive Loads: Control of heating elements, lighting systems, and other non-inductive loads (rated up to 40 A AC-1).
• Remote Control: Allows the main power circuit to be controlled remotely using a low-power control signal (95-130 V AC/DC).
• Signaling and Interlocking: The integrated 1 NO + 1 NC auxiliary contacts are used for status feedback to the control system (e.g., PLC) or for electrical interlocking with other devices.
