Function

The 3RA2922-1AA00 adapter acts as an intermediary component to mechanically join a circuit breaker (e.g., $3\text{RV}2$) and a contactor (e.g., $3\text{RT}2$) and mount the resulting load feeder combination securely to the mounting surface or a $35\text{ mm}$ DIN rail. This connection is typically part of a pre-assembled kit or a system for on-site assembly, promoting uniformity and professionalism in panel design.
