The interrupting rating holds at 100 kA across the 240 V to 690 V AC range, so this breaker can be placed downstream of a high-capacity transformer without requiring a current-limiting upstream device — a real advantage when the panel SCCR needs to stay above 65 kA. ## Mounting and wiring — DIN rail footprint and terminal capacity The breaker snaps onto a 35 mm DIN rail per DIN EN 50022 and occupies a 45 mm width, 97 mm height, 96 mm depth footprint — a standard SIRIUS frame that leaves 0 mm clearance needed at the back or sides, so it rows tightly with contactors in a motor starter cell. Screw-type terminals on the main circuit accept 2x (0.5 to 1.5 mm²) solid or 2x (1 to 2.5 mm²) stranded, with AWG equivalents of 2x (14 to 10) for the main contacts. The auxiliary and control circuit terminals use the same screw-type format, keeping the wire range consistent across the assembly. Front-side IP20 protection means the busbars and terminals are touch-safe once the cover is on, but the breaker is not sealed against washdown — keep it inside the enclosure, not on the machine frame. ## Lifecycle and compliance — current production, RoHS dated The 3RV1021-0GA15-ZX95 carries a lifecycle stage of current production, so it remains a standard catalog item for new panel builds and BOM-freeze projects — no last-time-buy clock is running. RoHS compliance is documented with a substance prohibition date of 01.05.2012, covering the EU directive scope. The storage and transport temperature range of -50 to +80 °C exceeds the operating range of -20 to +60 °C, which is typical for a component that must survive warehouse cold soak but run inside a ventilated enclosure. ## Auxiliary switch provision and operating frequency The breaker accepts a transverse-design auxiliary switch — useful for remote status indication or safety-circuit feedback without adding an external interposing relay. The maximum switching frequency under AC-3 duty is 15 operations per hour, which governs cycling applications like reversing starter or jogging stations.","metaTitle":"Siemens 3RV1021-0GA15-ZX95 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens 3RV1021-0GA15-ZX95 SIRIUS motor protection circuit breaker, 0.63 A rated current, CLASS 10 trip class, 100 kA breaking capacity at 400 V AC.
