Product details

The 5SY6606-7CC is a 4-module-width (72 mm) SENTRON miniature circuit breaker with a C-curve trip characteristic, rated 6 A at 230/400 V AC and 50/60 Hz.

At 40 °C ambient the continuous current rating derates to 5.51 A; at 45 °C to 5.25 A; at 50 °C to 4.97 A; at 55 °C to 4.69 A. The breaker is rated for -40 °C to 75 °C ambient, with humidity limits of 95% up to 55 °C, 55% up to 70 °C, and 35% at 75 °C.

Breaking capacity and approvals

Rated breaking capacity is 6 kA per EN 60898 and 5 kA per UL 1077 / CSA C22.2 No. 235. Sealable for lockout/tagout.

Frequently asked questions

What is 5SY6606-7CC's depth?

76 mm overall depth, with a 70 mm installation depth into the enclosure.

What is 5SY6606-7CC's width?

72 mm, which corresponds to 4 modular width units on a DIN rail.

What compliance documentation is available for 5SY6606-7CC?

The breaker carries IEC 60898 (6 kA) and UL 1077 / CSA C22.2 No. 235 (5 kA) ratings. It is halogen-free and silicon-free. Standard SENTRON documentation includes RoHS and REACH declarations.

Where can I buy 5SY6606-7CC?

Sourced and quoted to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time.

Will 5SY6606-7CC drop into a panel specified around 5SY7210-7CC?

Both are 4-module SENTRON breakers with the same 72 mm width and 76 mm depth, so the mechanical fit and DIN-rail footprint are identical. The electrical difference is the rating and curve — the 5SY7210-7CC is a 10 A B-curve, while this is a 6 A C-curve. No rewiring is needed if the panel's busbar and load terminals match the 6 A C-curve rating.
