Product details

The Siemens SIRIUS 3RT2926-1JK00 is a varistor-type surge suppressor with a built-in LED indicator, designed to clip directly onto S0-size contactors in the 3RT2.2 family. It handles control supply voltages of 48–127 V AC at 50/60 Hz and 24–70 V DC, making it a straightforward add-on for suppressing coil transients on the line side of a contactor.

The 12 mm depth and 30 mm width let this suppressor nestle alongside the contactor without stealing extra DIN-rail space — the clip-on fastening method snaps it onto the contactor's own mounting foot, so it doesn't consume a separate rail position. The storage range of -40 to +80 °C covers shipping and spares storage in unheated warehouses.

Frequently asked questions

How do I get current pricing and availability for 3RT2926-1JK00?

We source the 3RT2926-1JK00 to order against an RFQ. Submit a request and we'll confirm current pricing and availability at quote time.

What is the depth of 3RT2926-1JK00?

The 3RT2926-1JK00 has a listed depth of 12 mm, which lets it sit flush alongside the S0 contactor without protruding past the contactor body.

What is the width of 3RT2926-1JK00?

The 3RT2926-1JK00 has a listed width of 30 mm, matching the footprint of the S0 contactor it clips onto.

Will 3RT2926-1JK00 drop into a panel that was specified around 3RT1016-1AG61 without rewiring?

No — the 3RT2926-1JK00 is a varistor surge suppressor designed for S0-size contactors (3RT2.2 family), while the 3RT1016-1AG61 is a power contactor in the S00 frame. They serve different functions and have different mounting footprints, so they are not drop-in replacements.

What compliance documentation does Siemens provide for 3RT2926-1JK00?

As a Siemens SIRIUS component, the 3RT2926-1JK00 typically ships with a declaration of conformity covering the applicable EU directives and standards. Specific documentation (RoHS, REACH, UL, IEC) is available on request — we can include it with the quote.
