Siemens 3RT2926-1ER00 Surge Suppressor Diode Combination 24V DC for 3RT2.2 Contactors Original Brand New

Overview

The Siemens 3RT2926-1ER00 belongs to the Sirius Innovation family of industrial control products. It is specifically engineered to be plugged into the front of Size S0 contactors. By using a diode combination, this module ensures that the opening of the contactor coil does not induce high-voltage transients that could damage PLC outputs or other delicate circuitry.

Benefit

• Enhanced System Reliability: Prevents inductive interference from disrupting nearby electronic components.

• Space-Saving Design: Snaps directly onto the contactor, requiring no additional rail space.

• Plug-and-Play Installation: Easily retrofitted to existing 3RT2.2 series contactors without complex wiring.

• Optimized for DC: Specifically tuned for 24V DC control circuits for maximum suppression efficiency.

Technical Function

• Voltage Limiting: Attenuates the back-EMF (electromotive force) generated when the contactor coil is de-energized.

• Diode Combination: Provides a clean "clamping" effect, ensuring the voltage does not exceed the breakdown limits of the driving circuit.

• Compatibility: Precision-engineered for the Siemens 3RT2.2 (Size S0) contactor range.
