Transformer-protection circuit breaker, Size S00
Rated breaking capacity reaches 100 kA at 240 V AC, 400 V AC, and 500 V AC, dropping to 10 kA at 690 V AC. At 400 V the unit is rated to clear a 25 A gG fuse-limit; at 500 V that rises to 32 A gG, and at 690 V it returns to 25 A gG.
Mounting position is any, which simplifies panel layout. Required clearance: 50 mm upwards, 50 mm downwards, 30 mm at the sides, and zero forwards or backwards — so it can sit flush against a backplate or enclosure wall. The 45 mm width and 97 mm depth fit standard S00 footprint, meaning a panel originally laid out for a 3RV2011-0BA20 or 3RV2021-1FA15 accepts this unit without re-drilling the DIN rail or re-routing wiring, provided the terminal scheme (spring-loaded terminals for the main current circuit) matches the existing lug arrangement.
The lifecycle stage is listed as current — this is an active, in-production catalog number within the SIRIUS family. No end-of-life notification or last-time-buy date is available.
