Siemens 3RT2924-5AC11 Contactor Coil 24V AC, 60Hz, SIRIUS 3RT2 S0 Original Brand New

Overview: Siemens 3RT2924-5AC11 Magnetic Coil for SIRIUS 3RT2 Contactors

The Siemens 3RT2924-5AC11 is a high-quality replacement magnetic coil designed specifically for the Siemens SIRIUS 3RT2 line of power contactors, particularly models in Size S0. This crucial component ensures the reliable electrical control and operation of your contactor, meeting the high standards of the SIRIUS modular system. It is engineered for standard industrial applications requiring a 24 Volt alternating current (VAC) control voltage at a 60 Hz frequency.

Key Technical Specification

• Product: Magnetic Coil (Solenoid Coil)
• Part Number: 3RT2924-5AC11
• Manufacturer: Siemens
• Series: SIRIUS 3RT2
• Control Supply Voltage: 24 V AC, 60 Hz
• Applicable Contactor Sizes: S0 (typically for contactors up to 7.5 kW / 10 HP at 400V)
• Compatibility: Designed for use with specific 3RT202*-.*A contactors, including:
  • 3RT2023-.*A
  • 3RT2024-.*A
  • 3RT2025-.*A
• Terminal Type: For contactors with screw terminal connections.

Function

The 3RT2924-5AC11 magnetic coil is the activating mechanism of the power contactor. When the 24 V AC, 60 Hz control voltage is applied to the coil, it generates a magnetic field. This field pulls the contactor’s armature, closing the main power contacts to establish the circuit for motor control or switching. When the voltage is removed, the magnetic field collapses, and a spring opens the contacts, de-energizing the circuit.

Benefit

• Reliable Performance: Genuine Siemens component ensures faultless compatibility and consistent, long-term switching reliability for your contactor.
• Ease of Replacement: Designed for simple and fast installation as a spare part or replacement coil, minimizing downtime.
• Optimal Compatibility: Perfectly matched electrical and mechanical specifications for the listed SIRIUS 3RT2 Size S0 contactors.
• Industry Standard: Part of the globally recognized Siemens SIRIUS modular system, ensuring quality and availability.
