SIEMENS 3RV29011F Transverse Contact Block 2NO
Transverse auxiliary contact block with two normally open contacts and screw terminals for SIRIUS 3RV2 motor starter protectors, IP20 rated
- Two normally open contacts expand control circuits
- Screw terminals simplify wiring and maintenance
- IP20 rating protects against solid objects
- Designed for SIRIUS 3RV2 motor starter protectors
- Auxiliary contact block adds switching flexibility
SIRIUS 3RV2 Motor Starter Accessory
This transverse contact block fits SIRIUS 3RV2 motor starter protectors and adds two normally open auxiliary contacts. It mounts directly to the starter and uses screw terminals for secure wiring connections. The block carries an IP20 rating and is supplied new.
For control-panel builders adding signalling
Engineers expanding a 3RV2 starter with extra status contacts will find this block compatible and straightforward to install. Installations that require normally closed contacts or a different contact count must select another accessory. Panels using non-SIRIUS starter series cannot accept this mounting format.
Two normally open contacts on screw terminals
The block provides exactly two normally open contacts and connects via screw terminals. That contact arrangement and terminal type are the specifications that determine whether the part matches the control-circuit design.
Highlights
- Two normally open contacts expand control circuits
- Screw terminals simplify wiring and maintenance
- IP20 rating protects against solid objects
- Designed for SIRIUS 3RV2 motor starter protectors
- Auxiliary contact block adds switching flexibility

Questions about this item
What is the maximum number of normally open contacts this block adds to a 3RV2 motor starter protector?
The block adds two normally open contacts, giving a total of two additional NO circuits for auxiliary signalling or control duties.
How much heat does the contact block generate when the starter runs continuously under load?
The auxiliary block itself carries only low‑level control current, so its own heat contribution is negligible compared with the main power poles of the starter.
Which SIRIUS 3RV2 starter frame sizes accept this transverse auxiliary block?
The block is designed for the SIRIUS 3RV2 series motor starter protectors and mounts directly on the transverse accessory rail of those devices.
