The 11 kW at 400 V figure gives you the typical 3-phase induction motor size this breaker covers at that voltage. ## Breaking capacity and fault clearing Rated breaking capacity is 100 kA at 240 V AC, 50 kA at 400 V AC, 10 kA at 500 V AC, and 4 kA at 690 V AC. The 6 000 V rated surge voltage resistance (impulse withstand) means it holds off transients common in industrial environments without flashover between phases or to ground. ## Trip class and motor protection features Ground fault detection is not included on this variant (the ZW97 suffix indicates a special version without that function). If ground-fault protection is required, a separate module or a different breaker from the 3RV2 family would be needed. ## Physical integration and wiring Width is 45 mm (3 module spaces on a DIN rail), depth 96 mm, height 97 mm. Mounting position is any orientation. Screw terminals for main and auxiliary circuits accept 2x (1 to 2.5 mm²) solid or stranded, or 2x (2.5 to 6 mm²) — typical for motor branch circuits up to 6 mm² (roughly 10 AWG). The 0 mm backwards clearance and 0 mm side clearance mean it can be mounted flush against adjacent devices or the panel wall. Shock resistance is 25 g for 11 ms. RoHS compliance date is 01.05.2012 (substance prohibition per EU directive).","metaTitle":"Siemens 3RV1021-4DA10-ZW97 SIRIUS Motor Protection Breaker,","metaDescription":"Siemens 3RV1021-4DA10-ZW97 SIRIUS motor protection circuit breaker, 25 A continuous, 11 kW at 400 V, Class 10 trip.
