Rated operating voltage spans 20 to 690 V. The breaking capacity sits at 100 kA at 400 V and holds that same 100 kA at 240 V, 500 V, and 690 V — that's a flat high-fault rating across the common industrial voltages, meaning you don't have to derate for higher-voltage panels. That's standard for motor circuits, but here it's applied to transformer primary protection — the fast trip still allows for the magnetizing inrush on energization. Any mounting position is acceptable — horizontal, vertical, upside-down, doesn't matter for the thermal-magnetic trip. That's tight enough for dense panels. Dimensions: 45 mm wide, 106 mm tall, 97 mm deep. Main circuit connections use spring-loaded terminals — no screwdriver needed for the power wiring, just strip and push. ## Environmental and operating limits That's a wide storage range — fine for unheated warehouses or truck beds in winter. Maximum switching frequency at AC-3 duty: 15 operations per hour. That's not a high-cycling device — don't spec it for frequent switching applications like welding or rapid-start conveyors. It's meant for transformer primary protection where switching is infrequent.","metaTitle":"Siemens 3RV2411-1AA20 SIRIUS Circuit Breaker, Transformer Pr","metaDescription":"Siemens 3RV2411-1AA20 SIRIUS circuit breaker for transformer protection. 100 kA breaking capacity at 400 V, Class 10 trip, phase failure detection.

But the 3RV2411-1AA20 is designed for transformer protection, while the 3RV2011-0BA20 is a general motor protection breaker — the trip curves differ.
