It's designed for railway applications per the listing, and carries IP20 protection with conductors connected. Rated 1 A at 400 V AC, 50/60 Hz, with a maximum DC rating of 72 V. The 3-pole configuration (3P) means it switches all three phases simultaneously — no neutral pole. Energy limiting class 3 means it limits let-through energy well, which helps with downstream device coordination. Mounts on a quick-assembly system (DIN rail) — 3 width units wide at 54 mm, 90 mm tall, 76 mm deep with an installation depth of 70 mm. Combined terminals top and bottom, sealable, touch-protected. Halogen-free and silicon-free construction.","metaTitle":"Siemens 5SY4301-6CC11 SENTRON MCB, 1A B-Curve 3P 10kA","metaDescription":"Siemens 5SY4301-6CC11 SENTRON miniature circuit breaker, 1A rated, B-curve, 3-pole, 10kA breaking capacity per EN 60898, 400V AC.
