Product details

Side-mount auxiliary switch for 3RV breakers

The Siemens 3RV1901-1AA00-ZW97 is a side-mountable auxiliary switch block delivering one normally-open and one normally-closed contact set, designed for the SIRIUS 3RV series of circuit breakers in frame sizes S00 through S3. It clips onto the side of the breaker, so it adds status feedback without increasing the panel depth — the same footprint you already have for the 3RV breaker itself.

What it does and what it skips

This is a pure auxiliary contact block — no ground fault detection, no phase failure detection, no integrated auxiliary switch extension, and no removable terminal for the auxiliary circuit. If your application requires ground fault or phase loss monitoring, you need a separate monitoring relay or a different breaker variant; this block only signals the breaker's ON/OFF state.

RoHS compliance date is 07/01/2006, meaning it meets the EU RoHS directive for substances of concern as of that date.

Frequently asked questions

Where can I buy 3RV1901-1AA00-ZW97 and how do I get a price?

This part is sourced and quoted to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time.

What is 3RV1901-1AA00-ZW97's listed ground fault detection?

Ground fault detection is listed as No — this auxiliary switch block does not include ground fault monitoring.

Will 3RV1901-1AA00-ZW97 drop into a panel specified around 3RV5341-4LC10 without rewiring?

The 3RV1901-1AA00-ZW97 is a side-mount auxiliary switch for frame sizes S00–S3, while the 3RV5341-4LC10 is a size S3 circuit breaker with screw and snap-on DIN-rail mounting. The auxiliary switch is designed to clip onto the side of 3RV breakers including the S3 frame, so it should mount without panel rework — but verify the specific 3RV5341-4LC10 variant's auxiliary slot compatibility before ordering.

What compliance documentation does Siemens provide for 3RV1901-1AA00-ZW97?

The part carries a RoHS compliance date of 07/01/2006. Standard Siemens documentation for this series includes the CE declaration of conformity and the product datasheet; UL and IEC certifications are typically listed on the breaker itself and its accompanying documentation.
