Product details

Rated current and selectivity

The 10 kA breaking capacity per EN 60898 covers most commercial and light-industrial fault levels; the 5 kA rating per UL 1077 and CSA C22.2 No. 235 is the figure to use for North American panel schedules. At 40 °C the breaker carries 23.5 A before thermal derating; at 50 °C it holds 21.9 A, and at 55 °C it holds 21.05 A — so a 25 A breaker on a 20 A continuous load in a 50 °C panel is fine, but pushing a 24 A load at 55 °C will trip on thermal after sustained operation.

Snap-on DIN rail mount, any position. IP20 with connected conductors — this is a dry-location panel breaker, not for washdown environments. The quick-assembly system and sealable toggle let the panel builder lock out unauthorized operation after commissioning.

Frequently asked questions

What is the breaking capacity of 5SY4425-7CC?

10 kA per EN 60898 and 5 kA per UL 1077 / CSA C22.2 No. 235 — the lower figure governs for North American panel coordination.

Will 5SY4425-7CC drop into a panel specified around 5SY4304-7CV?

Both are 4-pole SENTRON MCBs on the same DIN-rail footprint with identical 72 mm width, so the mechanical swap is direct. The 5SY4425-7CC is a 25 A C-curve; the 5SY4304-7CV is a 4 A C-curve — the ampacity difference means the branch circuit must be re-evaluated for conductor and load coordination before substitution.
