Product details

It carries a 6 kA breaking capacity per EN 60898-1 and 30 kA per IEC 60947-2 — the higher IEC figure governs the fault-interruption capability when the part is applied under that standard, so for industrial panel designs specified to IEC 60947-2 you get a full 30 kA SCCR at 400 V.

The 2 MW (36 mm) width means it occupies two 18 mm modular units. Combined terminal top and bottom — line and load can enter from either end. The neutral conductor is not switched (2-pole but both poles are phase, no switched neutral). Ambient temperature range -40 °C to 75 °C, with derating above 55 °C: max 95% RH at 55 °C, 55% at 70 °C, 35% at 75 °C. Suitability marked for mechanical engineering and industry — standard industrial panel environment.

Frequently asked questions

What is the closest functional second-source to the 5SY6206-7?

The Siemens 5SL4363-7 is a direct functional equivalent: same 2-pole C-curve, same 6 kA / 30 kA breaking capacity, same 2 MW width. The housing design differs (SY vs SL) but the DIN-rail footprint, terminal layout, and ratings are interchangeable. No rewiring required for a swap.

What compliance documentation does the 5SY6206-7 carry?

The part is certified to IEC / EN 60898-1, IEC / EN 60947-2, UL 1077, and CSA C22.2 No. 235. It is halogen-free and silicon-free. Pollution degree 3, overvoltage category III. The UL 1077 listing is as a supplementary protector, not a UL 489 branch-circuit breaker.
