Product details

Rated values and breaking capacity

The Siemens 5SY6610-8CC is a SENTRON miniature circuit breaker (MCB) in a 4-pole 3P+N configuration, rated 10 A at 400 V AC. Breaking capacity is 6 kA per EN 60898 and 5 kA per UL 1077 / CSA C22.2 No.235.

Mounts via the quick-assembly system (DIN rail) in any position. Combined terminals top and bottom simplify busbar and outgoing wiring. The neutral conductor is switched (3P+N), so the breaker isolates all live poles including neutral — required in some national wiring rules for TN-S systems.

Compliant with EN 60898 for residential-type MCB performance and with UL 1077 / CSA C22.2 No.235 for supplementary protection in North America. The product designation per DIN EN 61346-2 and DIN EN 81346-2 is function code F (protective device).

Frequently asked questions

What is the breaking capacity of 5SY6610-8CC?

6 kA per EN 60898 at 400 V AC, and 5 kA per UL 1077 and CSA C22.2 No.235.

What is the difference between 5SY6610-8CC and 5SY7140-8CC?

The 5SY7140-8CC is a higher-current variant (14 A vs 10 A) in the same SENTRON 5SY6CC design series. Both share the same 4-pole 3P+N format, D-curve, and breaking capacity ratings. The 5SY6610-8CC is the correct choice for a 10 A branch circuit; the 5SY7140-8CC serves a 14 A load. Panel footprint and wiring are identical.

Where can I buy the 5SY6610-8CC?
