Auxiliary contact block for SIRIUS contactors
The SIEMENS 3RH29111MA11 adds one normally open and one normally closed contact to compatible SIRIUS 3RH2 contactor relays and 3RT2 contactors. It mounts on the front of the device and uses screw terminals for wiring. The block is rated for 690V AC and carries an IP20 rating.
Front-mount screw-terminal design
This auxiliary block installs directly onto the front face of supported contactors without additional brackets. The screw-terminal connection accepts standard ferrules or stripped wire for secure termination. Two contacts are provided in a single compact housing.
Fits frame sizes S00 through S3 and NEMA 0/00
The block is compatible with SIRIUS 3RH2 and 3RT2 series devices across frame sizes S00, S0, S2 and S3 as well as NEMA sizes 0 and 00. It expands control-circuit functionality without increasing the contactor footprint. Buyers needing more than two auxiliary contacts or a different mounting style will need a different accessory.
