Product details

The 5SY8416-7: The 30 kA rating at 400 V AC (IEC 60947-2) is the headline fault-interruption capability for industrial distribution panels. That figure governs selectivity with upstream devices — a 30 kA SCCR at the panelboard lets you coordinate with a 50 kA or 65 kA main breaker without cascading. The 15 kA DC rating at 60 V covers battery-backed or rectifier-fed circuits. The 5 kA UL 1077 rating is the supplementary-protector limit for North American installations where the MCB is not the sole branch-circuit overcurrent device.

Integration — DIN-rail fit, terminal details, and environmental limits

Combined top and bottom terminals simplify daisy-chaining busbars. Operating temperature spans -40 to 75 °C, with humidity derating above 55 °C (95% RH 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.

Frequently asked questions

Where can I buy the 5SY8416-7 and get a price?

The 5SY8416-7 is sourced to order against an RFQ through independent distribution. Submit a request for quote; availability and current pricing are confirmed at quote time.

What is the breaking capacity of the 5SY8416-7 at 400 V AC?

30 kA per IEC 60947-2 at 400 V AC. It also carries 15 kA at 60 V DC and 5 kA per UL 1077.

What standards does the 5SY8416-7 comply with?

It is certified to IEC/EN 60947-2 and UL 1077, with a pollution degree 3 rating and overvoltage category III.

Will the 5SY8416-7 drop into a panel specified for the 5SY5416-7?

Both are 4-pole C-curve MCBs in the SENTRON 5SY family with the same 72 mm width and DIN-rail mount. The 5SY8416-7 carries a higher 30 kA IEC breaking capacity versus the 5SY5416-7's typical 15 kA — verify the fault level at the panelboard before substituting.
