The 3VU9131-3AA00-0RE0: The 1NO+1NC contact configuration is the standard auxiliary contact block for signaling breaker status — the NO contact closes when the breaker trips or is manually switched on, the NC opens. The 0.5 MW width (roughly 12.5 mm) matches the existing 3VU13/16 breaker footprint, so it clips directly onto the side of the breaker without consuming additional DIN-rail space. No separate mounting bracket is needed.
