Siemens 3RT2926-5AH01 Contactor Coil 48V AC, SIRIUS S0 Original Brand New

Overview: Siemens 3RT2926-5AH01 Magnetic Coil

The Siemens 3RT2926-5AH01 is a high-quality, genuine replacement magnetic coil designed specifically for the SIRIUS 3RT2 series of power contactors, specifically those in Size S0 (up to 18.5 kW). This essential spare part ensures the reliable function of your motor control system by providing the necessary 48 V AC, 50 Hz control voltage to operate the contactor. It is designed for simple, quick replacement, minimizing downtime in industrial and automation environments.

Key Product Detail

• Part Number: 3RT2926-5AH01
• Brand: Siemens SIRIUS
• Type: Magnetic Coil / Solenoid Coil
• Control Voltage: 48 V AC (Alternating Current)
• Frequency: 50 Hz
• Contactor Size Compatibility: S0 (up to 18.5 kW)
• Terminal Type: Screw Terminal (typically on the contactor body)
• Typical Power Loss: 9.8 V·A (VA)

Function

The magnetic coil is the core electromagnetic component of a contactor. When the specified 48 V AC control voltage is applied to the 3RT2926-5AH01 coil, it generates a magnetic field. This field pulls the contactor’s armature, which in turn closes (or opens) the main contacts to switch power to a motor or other load. A functioning coil is vital for the correct operation, safety, and longevity of the entire contactor and the controlled system.

Benefit

• System Longevity: Restores the intended performance and operational life of your Siemens 3RT2 contactor.
• Perfect Fit: Guaranteed compatibility and seamless integration with SIRIUS 3RT2 Size S0 contactors.
• Cost-Effective Repair: Avoids the expense of replacing the entire contactor by allowing for a simple, focused component swap.
• Genuine Siemens Quality: Manufactured to strict quality standards, ensuring high contact reliability and prolonged endurance in demanding industrial applications.

Compatibility

This replacement coil is compatible with the following Siemens SIRIUS 3RT2 contactors, all of which are typically Size S0:

• 3RT2325-.A
• 3RT2.26-.A (e.g., 3RT2026-.A, 3RT2326-.A, 3RT2526-.A)
