The screw-and-snap-on fastening lets a panel builder pre-wire the terminals and snap the unit in last — no loose hardware inside the enclosure. Ground fault detection is not included — that stays external if the application requires it. ## SCCR headroom and fuse backup coordination At 690 V the interrupting rating drops to 4 kA, so a 690 V installation needs upstream fuse coordination; the evidence specifies gL/gG backup fuses: 63 A at 400 V, 50 A at 500 V, 40 A at 690 V. For motor branch circuits, the horsepower ratings per voltage tell you the maximum motor this breaker can back up: 2 hp at 230 V, 3 hp at 200–230 V, 8 hp at 460–480 V. These are the values a panel builder uses for UL 508A sizing — the breaker's own thermal setting must be adjusted to the motor FLA, not the transformer primary. Main circuit terminals are screw-type, accepting 2x 0.75–2.5 mm² solid/stranded or 2x 4 mm². The M3 screw size is standard for panel wiring; torque to the manufacturer's spec for the terminal material. Clearance distances: 50 mm upwards and downwards, 30 mm at the sides — no extra space needed forwards or backwards, which helps when the breaker sits against a gland plate or backplane. The Class 10 trip curve limits switching frequency to 15 operations per hour at AC-3 and AC-3e duty — adequate for transformer inrush cycles but not for frequent motor starting.","metaTitle":"Siemens 3RV2411-1KA10 SIRIUS Circuit Breaker, Class 10, 100","metaDescription":"Siemens 3RV2411-1KA10 SIRIUS circuit breaker for transformer protection.
