Product details

Breaking capacity is 6 kA per EN 60898; under UL 1077 and CSA C22.2 No. 235 it's rated 5 kA, so check your available fault current if the panel ships to a North American site. Current derating is published: 1.88 A at 40 °C ambient, 1.82 A at 45 °C, 1.75 A at 50 °C, 1.68 A at 55 °C. Humidity tolerance follows a stepped curve — 95% RH up to 55 °C, dropping to 35% RH at 75 °C — which governs sealed enclosures in washdown or outdoor cabinets.

That 6 mm difference is the arc chamber clearance — don't compress it against the backplane.

Frequently asked questions

What is the breaking capacity of the 5SY6502-8CC?

Rated 6 kA per EN 60898 and 5 kA per UL 1077 / CSA C22.2 No. 235. The lower UL/CSA figure is the one to use for North American fault-current coordination.

What does the D tripping characteristic mean for this breaker?

D-curve trips at 10 to 20 times the rated current (20 A to 40 A magnetic trip), which suits loads with high inrush — small motors, transformers, or solenoid banks. It avoids nuisance trips that a B or C curve would see on startup.

Will the 5SY6502-8CC fit a panel designed for the 5SY7206-7CC without rewiring?

Both are 2-module-width SENTRON breakers on the same DIN-rail footprint, so mechanical fit is identical. The difference is the tripping curve and rating: the 5SY7206-7CC is a C-curve at a higher ampacity. No wiring change needed for the rail or busbar position, but verify the load's inrush profile against the curve and the conductor sizing against the ampacity.

Where can I buy the 5SY6502-8CC?
