Its breaking capacity reaches 100 kA at 400 V AC (and at 240 V and 500 V AC as well), dropping to 2 kA at 690 V AC — so in a 400 V panel this breaker can interrupt fault currents up to 100 kA without upstream fuses, which simplifies coordination in high-fault installations. No ground-fault detection on this variant. Front-face protection is IP20, suitable for enclosed panel use; no washdown rating. Any mounting position is allowed. Terminals accept solid or stranded conductors: 2× (0.5…1.5 mm²) and 2× (0.75…2.5 mm²) per pole, with AWG equivalents 2× (18…14) for the main circuit. Shock rated at 25g for 11 ms. Maximum operating altitude 2 000 m. Surge voltage resistance rated at 6 000 V. Mechanical endurance of the main contacts is typically 100 000 operations. Maximum switching rate at AC-3 duty is 15 operations per hour.","metaTitle":"Siemens 3RV1011-0KA10-0FJ0-ZX95 SIRIUS Motor Protection Circ","metaDescription":"Siemens SIRIUS 3RV1011-0KA10-0FJ0-ZX95 motor protection circuit breaker, 1.25 A continuous, CLASS 10 trip, 100 kA breaking capacity at 400 V AC.
