Breaking capacity reaches 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. Width is 45 mm, depth 96 mm, height 97 mm. Any mounting position allowed. No side clearance needed — 0 mm backwards and at the side — so it packs tight on the rail without derating. Front face is IP20, safe for finger-probe access inside an enclosed panel. ## Terminals and wiring Main circuit uses screw-type terminals. Accepts 2x (1 … 2.5 mm²) solid or stranded, and 2x (2.5 … 6 mm²) solid or stranded. AWG equivalent is 2x (14 … 10) for the main contacts. Finely stranded with core-end processing also accepted in the same ranges. That covers most panel-building wire sizes up to 6 mm² without needing ferrules for fine-stranded wire. Shock resistance rated at 25 g / 11 ms, which covers most industrial vibration environments. Mechanical endurance of the main contacts is 100,000 operations typical. No ground fault detection on this variant.","metaTitle":"Siemens 3RV1021-4AA10-ZW97 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens SIRIUS 3RV1021-4AA10-ZW97 motor protection circuit breaker, 16 A rated, 7.5 kW at 400 V, Class 10 trip, 50 kA breaking at 400 V AC.
