This essential component ensures the reliable operation of your industrial motor control applications by providing the necessary electromagnetic force to operate the main contacts.

Rated for a control supply voltage of 110V AC at both 50 Hz and 60 Hz, the 3RT2926-5AG21 coil is an indispensable spare part for maintaining and repairing your existing Siemens motor starters and contactor assemblies.

Key Benefit

• Guaranteed Compatibility: Specifically engineered as a direct replacement for the control circuit of Siemens SIRIUS 3RT2 contactors, ensuring a perfect fit and seamless integration.
• Reliable Performance: Maintains the high standards of the SIRIUS system, offering consistent and dependable switching operations for motor control up to 18.5 kW (Size S0 contactors).
• Optimal AC Control: Features a dual-frequency rating of 110V AC (50/60 Hz), making it suitable for a wide range of industrial power systems globally.
• Simple Maintenance: As an easily replaceable spare part, it minimizes contactor downtime and simplifies maintenance procedures.

Function

The magnetic coil (or solenoid coil) is the core operational component in an electromechanical contactor. When the control supply voltage of 110V AC is applied to the coil terminals, it generates a magnetic field. This field pulls the armature (plunger) to overcome the spring force, which in turn causes the main and auxiliary contacts of the SIRIUS 3RT2 contactor to change state (typically closing the power contacts to start a motor). The 3RT2926-5AG21 is the spare part that restores this critical switching function to your contactor.

Application

This magnetic spare coil is essential for any industrial setup utilizing the compatible Siemens SIRIUS 3RT2 Size S0 contactors for:

• Motor control and starting (DOL/reversing starter setups)
• Switching resistive loads
• Industrial automation and control panels
• Any application requiring the activation of a compatible Siemens 3RT2 contactor.
