Product details

It breaks fault currents up to 15 kA per EN 60898 and 30 kA per IEC 60947-2, with a DC rating of 15 kA per IEC 60947-2.

Thermal derating — the real-world current

The 10 A rating holds at 35 °C ambient. At 40 °C it derates to 9.39 A, at 50 °C to 8.74 A, and at 60 °C to 8.04 A. Plan the load circuit accordingly.

Dimensions: 72 mm wide (4 modular width units), 90 mm tall, 76 mm deep, with an installation depth of 70 mm behind the panel face. Sealable, halogen-free, silicon-free construction — relevant for clean-room or food-grade zones where outgassing or contamination matters.

Frequently asked questions

What is the breaking capacity of 5SY7410-8?

15 kA per EN 60898, 30 kA per IEC 60947-2 at 400 V AC, and 15 kA per IEC 60947-2 for DC circuits.

What does the D tripping characteristic mean for this MCB?

The D curve trips magnetically at 10 to 20 times the rated current (In), so it passes the high inrush of motors, transformers, or welding equipment without opening, but clears a bolted fault fast.

Will 5SY7410-8 fit in a panel designed for 5SY4140-7?

Both are 4-pole SENTRON MCBs in the same 4-MW footprint (72 mm wide), so the physical drop-in is the same. The difference is the tripping curve — 5SY7410-8 is D curve (10–20× In), while 5SY4140-7 is a different characteristic. Verify the curve matches your load before swapping.
