The Siemens 5SL3401-7 is a SENTRON 5SL3 miniature circuit breaker rated 1 A at 400 V AC with a C tripping curve and a 4.5 kA breaking capacity per EN 60898 and IEC 60947-2. Four poles, 4 width units (72 mm), and IP20 with connected conductors — standard for residential and infrastructure panelboards.
Energy limiting class 3 for good let-through energy reduction. No neutral conductor switching (4P without switched neutral).
The 5SL3401-7 is sourced to order against an RFQ through independent distribution. Submit a request for quote; availability and current pricing are confirmed at that time.
The depth is 76 mm, with an installation depth of 70 mm.
The width is 72 mm, which corresponds to 4 width units on a DIN rail.
Both are 4-pole SENTRON 5SL series breakers with the same 72 mm width and DIN-rail mounting, so the footprint is identical. However, the 5SL3401-7 is a 1 A C-curve unit, while the 5SL3205-7MB is a different rating — confirm the circuit's load current and tripping curve before swapping.
