At 240 V it is also 100 kA; at 500 V it drops to 42 kA; at 690 V it is 4 kA. For most 400 V industrial panels fed by a 1 MVA transformer, 100 kA gives comfortable SCCR headroom without needing a current-limiting upstream fuse. ## Mounting and wiring — panel-fit details That is a spring cage, not a screw clamp; strip length and ferrule use matter for consistent pull-out force. Mounting position is any, so vertical or horizontal panel layouts work. Clearance requirements: 50 mm above and below, 30 mm to the sides, zero forward or backward.","metaTitle":"Siemens 3RV2011-1JA20 SIRIUS Circuit Breaker, Class 10, 100","metaDescription":"Siemens SIRIUS 3RV2011-1JA20 motor protection circuit breaker, Class 10 trip, 100 kA breaking capacity at 400 V AC, spring-loaded terminals, DIN rail mount.
