The 100 kA breaking capacity at 400 V AC means this device can safely interrupt a bolted fault on a high-capacity distribution panel without upstream fuses needing to clear first; at 690 V the rating drops to 6 kA, which still covers most industrial motor branch circuits on 690 V systems. The 1.5 kW motor rating at 400 V gives a direct sizing reference for a standard 4-pole induction motor. The 45 mm width occupies two standard module positions on the rail. Depth is 96 mm, height 97 mm. Mounting position is any orientation. The IP20 front protection is typical for inside-enclosure use. Main circuit terminals are screw-type, accepting solid or stranded conductors: 2x (1... 2.5 mm²) or 2x (2.5... 6 mm²) per pole. AWG equivalents are 2x (14... 10). No auxiliary contacts are included as standard.","metaTitle":"Siemens 3RV1021-1FA10-0FJ0-ZX95 SIRIUS Motor Protection Brea","metaDescription":"Siemens SIRIUS 3RV1021-1FA10-0FJ0-ZX95 motor protection circuit breaker. 5 A continuous, CLASS 10, 100 kA breaking at 400 V.
