The SIEMENS 3RH1921-1XA20-0PA0 is an auxiliary contact block with 2 normally open contacts, designed for snap-on mounting to the SIRIUS 3RH2 contactor series. It expands the control circuit switching capacity without adding a separate contactor.
Snaps directly onto the front or side of the 3RH2 contactor body, occupying a single DIN-rail module width. The 2 NO contacts are electrically isolated from the coil circuit, allowing separate wiring for feedback or interlock signals.
This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
Within the same SIRIUS 3RH2 family, other auxiliary contact blocks with different contact configurations (e.g., 1 NO + 1 NC) exist, but no pin-compatible direct replacement with identical 2 NO arrangement is listed as an official substitute.
Alternative models and sibling configurations in the same Siemens series. For obsolete or discontinued parts, these models can serve as compatible replacements or functional alternatives for plant maintenance.
