The 100 kA breaking capacity at 400 V AC gives it enough interrupting capability to sit on a high-fault panel without needing upstream fuses; the same rating holds at 240 V and 500 V. Any mounting position is allowed, so vertical or horizontal rail orientation works in tight enclosures. The lifecycle stage for this order code is current production. That means it is still an active catalog item from Siemens, not a phase-out or NRND part. For a BOM line that calls out 3RV2021-1GA10-ZW97, the fit is confirmed by the Trip Class 10 and the 100 kA SCCR at 400 V — the two ratings that govern motor protection coordination. ## Deployment context The 45 mm width and 97 mm depth fit the standard 60 mm deep enclosure profile — no need for a deep gland plate. The screw-type terminals on the main current circuit accept solid or stranded conductors up to 2×10 mm², which covers the wire range for most motor circuits up to the 5 hp rating at 575/600 V.","metaTitle":"Siemens 3RV2021-1GA10-ZW97 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens SIRIUS 3RV2021-1GA10-ZW97 motor protection circuit breaker.
