The gL/gG fuse backup ratings tell you what upstream fuse lets the breaker still coordinate: 50 A at 400 V, 40 A at 500 V, 35 A at 690 V. If you're sizing a feeder, those are the max fuse ratings that preserve the breaker's short-circuit performance. The closest functional sibling is the 3RV2021-1GA25, which is a physically larger frame (S2 vs S0) with higher current ratings. The 3RV2011-1GA20-ZX95 is the S0 frame, 45 mm wide, 97 mm deep, 106 mm tall. If a panel was laid out for the 3RV2021-1GA25, this won't drop in without re-drilling — the mounting footprint and terminal spacing differ. ## Wiring and environmental limits Mounting position is any, which helps in tight enclosures. Clearance requirements: 50 mm upwards, 50 mm downwards, 30 mm at the sides, zero forwards and backwards. That 50 mm top/bottom gap is for arc-chute venting — don't cram it against a panel wall.","metaTitle":"Siemens 3RV2011-1GA20-ZX95 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens 3RV2011-1GA20-ZX95 SIRIUS motor protection circuit breaker, Trip Class 10, 100 kA breaking capacity at 400 V.
