It snaps onto a 35 mm DIN rail per EN 50022 and occupies 45 mm of panel width — a standard 1.5-module footprint that leaves room for adjacent contactors or overloads in a motor starter lineup. ## Sourcing & lifecycle — current production, quoted to order The -ZW96 suffix indicates a special version; verify the exact variant against your BOM line. Standard documentation (RoHS compliance dated 01.05.2012, CE, UL/CSA) applies. ## Terminal capacity and wiring — screw-type, dual conductor Main and auxiliary circuits use screw-type terminals. Each pole accepts two conductors: solid or stranded wire from 1 to 2.5 mm² in one clamp, and 2.5 to 6 mm² in the second. For AWG, that translates to 2x (14–10) per terminal. Finely stranded wire with ferrule is accepted in the same ranges. No special crimp tool is required beyond standard ferruling. Zero clearance required at the sides or rear — the breaker can be mounted flush against adjacent devices or the panel backplane. Depth is 96 mm, height 97 mm. Mounting position is unrestricted, which simplifies layout in crowded enclosures. The breaker withstands 25g shock for 11 ms — suitable for machine-mounted applications with vibration. Maximum switching frequency in AC-3 duty is 15 operations per hour, which governs cycling of motor start/stop sequences. Power dissipation at rated current is 7.25 W total (2.4 W per pole) in hot operating state. This heat must be considered in sealed enclosures; derating may apply above 40 °C ambient.","metaTitle":"Siemens 3RV1021-0HA10-ZW96 SIRIUS Motor Protection CB, 0.8 A","metaDescription":"Siemens 3RV1021-0HA10-ZW96 SIRIUS motor protection circuit breaker, 0.8 A continuous current, Class 10 trip, 100 kA breaking capacity at 400 V.
