The breaker carries approvals to IEC / EN 60898-1, IEC / EN 60947-2, and UL 1077 / CSA C22.2 No. 235. That means it is accepted in European (CE-marked) and North American (UL/CSA) installations — a single SKU for multi-region panels. Energy limitation class 3 limits let-through energy, reducing downstream damage on a fault. No neutral conductor switching; this is a straight 3-pole device for line-side protection only.

Frequently asked questions
Where can I buy 5SY4363-6 and how do I get a price?
The part is available to quote on request. Submit an RFQ through this listing; availability and current pricing are confirmed at quote time. No stock count or price is displayed here.
Will 5SY4363-6 drop into a panel specified around 5SY4140-7 without rewiring?
No. The 5SY4140-7 is a different pole/current variant in the same SENTRON family, but the 5SY4363-6 is a 3-pole B-curve breaker with a specific interrupting capacity and terminal layout. It shares the same DIN-rail footprint (3 MW, 54 mm wide) but the electrical ratings differ — verify the branch circuit requirements before substituting.
What compliance documentation does Siemens provide for 5SY4363-6?
The breaker is certified to IEC / EN 60898-1, IEC / EN 60947-2, and UL 1077 / CSA C22.2 No. 235. It is halogen-free and silicon-free. Standard RoHS and REACH declarations are available from Siemens upon request.
