Breaking capacity is 100 kA at 240 V and 400 V AC, dropping to 42 kA at 500 V and 6 kA at 690 V. No ground fault detection on this variant. Width is 45 mm, height 97 mm, depth 96 mm — fits a standard 45 mm module slot. Mounting position is any, which helps in tight enclosures. Terminals are screw-type for the main circuit, accepting solid or stranded conductors: 2×(1…2.5 mm²) and 2×(2.5…6 mm²), or AWG 14–10. Front face is IP20, so finger-safe in an enclosed panel. Power dissipation is 9.25 W total in hot operating state, or 3.1 W per pole. Shock resistance rated at 25g / 11 ms. Mechanical endurance of main contacts is 100,000 operations typical.","metaTitle":"Siemens 3RV1021-1KA10-0FJ0-ZX95 SIRIUS Motor Protection CB,","metaDescription":"Siemens SIRIUS 3RV1021-1KA10-0FJ0-ZX95 motor protection circuit breaker, 12.5 A continuous, CLASS 10 trip, 100 kA breaking at 400 V AC.
