Any mounting position works, which helps in tight enclosures where you can't guarantee vertical. At 400 V, the magnetic short-circuit release is coordinated with a gG 63 A upstream fuse; at 500 V, that drops to gG 50 A. That's the selectivity window — the breaker's instantaneous trip will clear a fault before the upstream fuse blows, as long as the fuse is sized to those limits. For motor full-load current, the breaker is rated 25 A at both 480 V and 600 V, which covers a 15 hp motor at 460/480 V and a 20 hp motor at 575/600 V. At 230 V it's good for 7.5 hp. The maximum switching rate in AC-3 duty (motor starting) is 15 operations per hour. That's fine for a pump or fan that cycles a few times an hour — not for a jogging or inching application where you're hitting the starter every 30 seconds. For high-cycle loads, step up to a contactor rated for 600+ ops/hr and let the breaker just provide backup protection. ## Panel Fit — What Goes Where That's the standard S0 footprint — same as the base 3RV2023-4DA10. The ZX95 suffix indicates a special version (customer-specific variant or packaging), but the mechanical dimensions and mounting are identical. If you're replacing a 3RV2023-4DA10 in an existing panel, this drops straight in — same screw-terminal layout, same DIN rail clip, same busbar compatibility. Clearance requirements: 50 mm upward and downward, 30 mm to the side, zero forward clearance needed. That's tight enough to stack breakers in a multi-motor panel without wasting rail space. Terminals accept solid or stranded wire: 2×(1 to 2.5 mm²) or 2×(2.5 to 10 mm²), with M4 screws on the main contacts.","metaTitle":"Siemens 3RV2023-4DA10-ZX95 SIRIUS Motor Protection Circuit B","metaDescription":"Siemens 3RV2023-4DA10-ZX95 SIRIUS motor protection circuit breaker, size S0, Class 10 trip, 45 mm wide, phase failure detection.
