The 45 mm wide body snaps onto a 35 mm DIN rail (DIN EN 50022) and stands 97 mm tall by 96 mm deep, so it fits a standard enclosure footprint with room for side-by-side auxiliaries. ## Panel Fit & Wiring The 45 mm width leaves space for a full row of auxiliaries or a contactor alongside. Screw-type terminals on the main circuit accept 2x (0.5…1.5 mm²) solid or 2x (1…2.5 mm²) stranded; the auxiliary circuit uses the same terminal style. No side clearance needed, zero backwards clearance — you can pack it tight. Shock-rated to 25g / 11 ms, so it survives shipping and moderate vibration on a machine frame. If you're driving a high-inertia load that needs a longer ramp, you'd step up to CLASS 20 or CLASS 30. Phase-failure detection is on by default — no extra module needed. Ground-fault detection is not included (that's a separate device if your application requires it). The auxiliary switch is transverse and field-installable, so you can add a remote trip-indication contact without pulling the breaker.","metaTitle":"Siemens 3RV1021-4AA15-ZW97 SIRIUS Motor-Protective Circuit B","metaDescription":"Siemens SIRIUS 3RV1021-4AA15-ZW97 motor-protective circuit breaker, 16 A continuous, 50 kA at 400 V AC, CLASS 10 trip.
