Product details

Breaking capacity is 10 kA per EN 60898 and 15 kA per IEC 60947-2 at 400 V AC. Rated insulation voltage (Ui) is 440 V AC, so it's comfortable on 400 V line-to-line systems with margin. For DC circuits, it's rated 60 V maximum, which covers 48 V control buses and small battery banks. IP20 with connected conductors (IP40 in the handle area) is standard for enclosed panel mount; no washdown rating, so keep it behind the gland plate.

Integration — DIN rail, terminals, environment

That covers unheated warehouses, outdoor cabinets in temperate climates, and the heat rise inside a packed panel. Vibration resistance is 50 m/s² at 25–150 Hz and 60 m/s² at 35 Hz (4 s) — enough for machine-mounted subpanels on conveyors or presses.

Frequently asked questions

Where can I buy 5SJ4306-8HG41 and how do I get a price?

This part is sourced and quoted to order through independent distribution. Submit an RFQ; availability and current pricing are confirmed at quote time.

What is 5SJ4306-8HG41's breaking capacity at 400 V?

10 kA per EN 60898 and 15 kA per IEC 60947-2 at 400 V AC. The IEC figure is the one to use for industrial panel coordination.

Will 5SJ4306-8HG41 drop into a panel specified around 5SY4304-7CV without rewiring?

Both are 3-pole MCBs on the same DIN-rail footprint, but the 5SJ4 series uses combined screw-clamp terminals while the 5SY series may differ in terminal type and torque. Check the terminal compatibility on your existing busbars and ring lugs before swapping — the physical rail fit is identical, but the connection method may require a different ferrule or adapter.
