Siemens 3RT1926-1TR00 Diode Surge Suppressor

Product Positioning

The 3RT1926-1TR00 is a coil surge suppression accessory designed specifically for Siemens SIRIUS S0 size contactors. It uses an internal diode assembly and does not include an indicator light. When the 24V DC coil is de-energized, it can effectively suppress induced surge voltage, protect other semiconductor components and relay contacts in the control circuit, and improve the overall system stability.

Core Product Advantages and Features

Diode surge suppression design

The induced surge generated at the instant the diode combination absorbs the coil when the power is cut off.

Simple design without indicator lights

It does not include LED indicator lights, has a simple structure, and is low in cost.

Applicable to 24V DC coil

Designed specifically for 24V DC coil control circuits.

Bottom plug-in installation

It can be installed directly from below the contactor without additional wiring.

Applicable to S0 size

Compatible with Siemens SIRIUS S0 size series contactors.

Original factory quality

Made in the Czech Republic, with stable and reliable quality.
