Product details

Mounting & Integration

The IP20 rating applies only with connected conductors — the breaker body itself is finger-safe but not sealed against dust ingress when the terminals are open.

Environmental & Compliance

Rated for ambient temperatures from -40 °C to 75 °C, with a derating curve for continuous load above 55 °C (95 % humidity at 55 °C, 55 % at 70 °C, 35 % at 75 °C). Vibration resistance per IEC 60068-2-6: ±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz — this is the spec that qualifies it for onboard rail and shipboard panels where constant vibration is present.

Frequently asked questions

What is the closest functional second-source to 5SY4106-7CC11?

The 5SY4101-7CV is a 1-pole C-curve MCB from the same SENTRON 5SY4 family, but its interrupting rating and voltage ratings differ — verify the specific ratings against your BOM before substituting. The 5SY4106-7CC11 is the preferred part for 400 V AC, 10 kA applications.

Will 5SY4106-7CC11 drop into a panel specified around 5SY4101-7CV without rewiring?

Both are 1-pole, 18 mm wide, DIN-rail mounted MCBs with C characteristic, so the physical fit and wiring are identical. However, confirm that the interrupting capacity and voltage ratings of the 5SY4101-7CV match your application — the 5SY4106-7CC11 is rated 10 kA at 400 V AC; the 5SY4101-7CV may have different values.
