The Siemens 3RV2411-1EA20 is a SIRIUS circuit breaker specifically designed for transformer protection, with a rated value range of 20 to 690 V. It delivers a breaking capacity of 100 kA at both 240 V and 400 V, dropping to 4 kA at 690 V — the 100 kA figure at 400 V is the one that governs most industrial distribution panels, giving you headroom for high-fault installations. The Trip Class 10 characteristic means it trips fast enough to protect downstream transformer windings from sustained overloads during inrush, while still allowing normal magnetizing current peaks.
