Product details

The 5SY7116-8: This MCB is certified to IEC / EN 60898-1 for residential-type installations and IEC / EN 60947-2 for industrial applications, plus UL 1077 for supplementary protection in North America. It also carries CSA C22.2 No. 235. Pollution degree 3, overvoltage category III. The sealable design allows a lead seal or tamper-evident tag to lock the toggle position — useful for safety circuits or rental-metered panels.

Ambient temperature range is -40 °C to 75 °C, with derating for humidity: max 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

What is the breaking capacity of 5SY7116-8?

Rated 15 kA per EN 60898 and 25 kA per IEC 60947-2 at 400 V AC. For DC circuits, it's 15 kA at 60 V (max 72 V) per IEC 60947-2. Under UL 1077, it's 5 kA at 440 V AC.

Where can I buy 5SY7116-8?

Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

What is the D-curve used for?

The D tripping characteristic (10–20× rated current) is designed for circuits with high inrush currents, such as motor starters, transformers, or capacitor banks, where a B or C curve would trip on startup.
