The Siemens SENTRON 5SY4206-7CC11 is a 2-pole miniature circuit breaker rated 6 A with a C tripping characteristic and a 10 kA breaking capacity at 400 V AC per EN 60898. Designed for railway applications, it handles both single-phase and multi-phase loads up to 440 V AC, and it also carries a maximum DC voltage rating of 72 V.
Energy limiting class 3 means it limits let-through energy under fault conditions, aiding downstream coordination. The sealable design allows panel builders to lock the toggle position after commissioning — useful for tamper-proof installations in public-access or railway substations.
