Siemens 3RT2926-5AU01 Magnetic Coil 240V AC, 50Hz for 3RT2 Series Contactors Original Brand New

Overview

The Siemens 3RT2926-5AU01 is a high-quality magnetic coil engineered to deliver reliable and efficient operation for Siemens 3RT2 series contactors. Designed for industrial applications requiring dependable switching performance, this coil operates at 240 V AC, 50 Hz, ensuring stable performance in demanding electrical control systems.

Compatible with a range of Siemens contactors—including 3RT2325-.A, 3RT2.26-.A, 3RT2.27-.A, and 3RT2028-.A—this magnetic coil provides seamless integration for maintenance, repair, and new installations across automation and control environments.

Function

The primary function of the 3RT2926-5AU01 coil is to generate the necessary electromagnetic force to operate the main contacts within the host contactor.

• Operation Principle: When the rated 240V AC (50Hz) control voltage is applied, the coil creates a magnetic field.
• Contactor Actuation: This field pulls the armature to close the main power circuit contacts, switching the motor or electrical load on.
• System Compatibility: Designed for use in electrical control panels, motor control centers, and automation systems requiring reliable switching capability.

Benefit & Key Features

• Guaranteed Compatibility: Direct replacement for Siemens contactor models 3RT2325-.A, 3RT2.26-.A, 3RT2.27-.A, and 3RT2028-.A (Size S0, up to 18.5 kW).
• Optimal Performance: Maintains the original specifications and reliability of the Siemens SIRIUS 3RT2 series.
• Easy Maintenance: A simple and quick solution for restoring contactor functionality when the existing coil fails.
• High Efficiency: Features a typical power loss of 9.8 VA at AC, contributing to energy efficiency in your control circuit.
