The Siemens SENTRON 5SY4310-7CC is a 3-pole miniature circuit breaker with C-curve tripping characteristic, rated 10 kA breaking capacity at 400 V AC according to EN 60898. For UL 1077 and CSA C22.2 No. 235 applications, the interrupting rating is 5 kA. The C-curve (5–10× In) is standard for protecting inductive loads like motor circuits, contactor coils, and small transformers where inrush current exceeds resistive load levels.

Frequently asked questions
How do I get current pricing and availability for 5SY4310-7CC?
Submit an RFQ against this order code. Pricing and stock are confirmed at quote time through our independent distribution channels.
Will 5SY4310-7CC drop into a panel specified around 5SY4310-7CV without rewiring?
Both are 3-pole SENTRON MCBs with the same DIN-rail footprint and 3-module width. The difference is the tripping characteristic: 5SY4310-7CC is C-curve, 5SY4310-7CV is not specified here. If the panel was designed for a C-curve breaker, it fits mechanically; verify the curve matches the original spec before swapping.
What compliance documentation does Siemens provide for 5SY4310-7CC?
The part carries ratings per EN 60898 (10 kA at 400 V AC) and UL 1077 / CSA C22.2 No. 235 (5 kA). It is halogen-free and silicon-free. Standard Siemens declarations for RoHS and REACH apply; request the specific declaration of conformity with your RFQ.
