At 0.3 A, the thermal element will hold the continuous load but trip quickly on sustained overloads above about 0.45 A. ## What the 400 V / 10 kA rating means in a railway panel The 400 V rated voltage covers standard European railway auxiliary supplies (typically 230/400 V AC from the train line or station substation). If the supply can deliver more than 10 kA, you need an upstream current-limiting device. The 3+N-pole configuration switches all three phases plus the neutral. In a railway context, the neutral is often distributed for single-phase control loads, so having the N pole switched ensures full isolation during maintenance. The DIN-rail footprint matches standard Siemens 5SY series accessories — busbars, shunt trips, and auxiliary contacts share the same rail spacing.","metaTitle":"Siemens 5SY4614-7CC11 MCB, 400V 10kA C 0.3A Railway","metaDescription":"Siemens 5SY4614-7CC11 miniature circuit breaker, 400V, 10kA, 3+N-pole, C characteristic, 0.3A for railway applications.
