At 54 mm wide (3 modular width units), 90 mm tall, and 76 mm deep (70 mm installation depth), it snaps onto standard DIN rail — any mounting position works, and the quick-assembly system means it clicks in without tools. The IP20 rating (with conductors connected) is typical for enclosed panel use; if you're pulling it for a field-service swap, the sealable design lets you lock the toggle position to prevent unauthorized toggling. It carries dual certification to IEC / EN 60898-1 (the household MCB standard) and IEC / EN 60947-2 (the industrial breaker standard), so it's accepted across both residential and industrial panels. UL/CSA listing is also on file at 5 kA per UL 1077 / CSA C22.2 No.235. The part is halogen-free and silicon-free — no silicone outgassing to foul contacts in sealed enclosures. Vibration resistance per IEC 60068-2-6 is ±1 mm at 5–25 Hz and 50 m/s² at 25–150 Hz, which covers most machine-mounted panels.","metaTitle":"Siemens 5SY4380-6 SENTRON MCB, 3P B-Curve, 10 kA","metaDescription":"Siemens 5SY4380-6 SENTRON miniature circuit breaker, 3-pole, B-curve, 10 kA (EN 60898-1) / 15 kA (IEC 60947-2).

Both share the same SENTRON DIN-rail footprint — same 54 mm width per pole, same quick-assembly mount — so the physical swap is straightforward, but verify the trip curve and interrupting rating match your branch circuit design."},{"question":"What compliance documentation does this brand provide for 5SY4380-6?","answer":"The breaker carries IEC/EN 60898-1 and IEC/EN 60947-2 certification, plus UL 1077 / CSA C22.2 No.235 listing.
