Product details

The Siemens 3RT5926-1TR00 is a diode combination accessory for SIRIUS contactors, size S0, designed for bottom mounting. It provides coil surge suppression without an integrated LED indicator — a clean fit for panels where the LED adds no value or creates a nuisance glow on de-energized circuits.

For a BOM line that needs this exact diode combination, the current lifecycle status means you can specify it without obsolescence risk in the near term.

Deployment Context

Mounts directly onto the bottom of a SIRIUS S0 contactor on a DIN rail or mounting plate. The diode combination fits within the contactor's envelope — no additional panel space required beyond the contactor itself. Wiring connects in parallel with the coil terminals; observe polarity if the diode is polarized (the part's own marking indicates cathode band).

Frequently asked questions

What is the closest alternative to 3RT5926-1TR00 in this component family?

The LED-equipped sibling (same S0 size, bottom-mount) adds a visual coil-state indicator. Choose the LED variant if panel troubleshooting requires a quick visual check; choose this non-LED version if the indicator would cause confusion or if the panel already has a separate status lamp.

What is 3RT5926-1TR00's listed description?

The official description is: Diode combination without LED, mounting onto contactors connect. at the bottom, size S0.
