It snaps onto a 35 mm DIN rail per DIN EN 50022 and accepts screw-type terminals for both main and auxiliary circuits — solid conductors up to 2.5 mm² and stranded up to 6 mm². The IP20 front protection keeps live parts behind the panel door, standard for motor control centers. This breaker delivers 100 kA breaking capacity at 240 V and 400 V AC, dropping to 42 kA at 500 V and 6 kA at 690 V AC. The 45 mm width (3 TE) fits standard panel layout grids. Depth is 96 mm, height 97 mm — check clearance behind the door if using deep enclosures. Auxiliary switch option is transverse design and can be added as a product extension.","metaTitle":"Siemens 3RV1021-1HA15 SIRIUS Motor Protective Circuit Breake","metaDescription":"Siemens 3RV1021-1HA15 SIRIUS motor-protective circuit breaker, 8 A rated current, Trip Class 10, 100 kA breaking capacity at 400 V AC.

The part is sourced to order via independent distribution; price and lead time are confirmed at quote time."},{"question":"What is the closest functional alternative — 3RV2021-1GA15?","answer":"The 3RV2021-1GA15 is a higher-rated sibling in the SIRIUS 3RV2 series. It shares the same DIN-rail footprint and screw-terminal design but carries a different continuous current rating and breaking capacity. Verify your motor FLA and available fault current before substituting — the 3RV1021-1HA15 is the correct 8 A, Class 10 variant for 3 kW at 400 V."},{"question":"What is the depth of 3RV1021-1HA15?","answer":"The depth is 96 mm. Combined with 45 mm width and 97 mm height, it fits standard 3-TE panel slots."},{"question":"What solid conductor sizes does the terminal accept?","answer":"The screw terminals accept 2x (0.5 to 1.5 mm²) and 2x (0.75 to 2.5 mm²) solid conductors. Stranded sizes are 2x (1 to 2.5 mm²) and 2x (2.5 to 6 mm²)."},{"question":"Does 3RV1021-1HA15 drop into a panel designed for 3RV2021-1GA15?","answer":"Both share the same 45 mm width and DIN-rail mounting, so the mechanical fit is identical. The electrical ratings differ — verify the load current and fault current before swapping. The 3RV1021-1HA15 is rated 8 A continuous with 100 kA at 400 V; the 3RV2021-1GA15 has its own rating curve."},{"question":"What compliance documentation is available for 3RV1021-1HA15?","answer":"RoHS compliance is confirmed with a substance prohibition date of 05/01/2012.
