You're looking at the B5-63 series, basically a workhorse MCB that handles the usual overload and short-circuit protection across residential, commercail, and light industrial setups — we ship these by the pallet most weeks.
Most buyers go with the 6kA breaking capacity for standard distribution boards, though if you're running inductive loads or motor circuits, the D-curve variant is what you'll want; the B and C types are better for general lighting and socket circuits.
230/400V rated voltge with a 500V insulation voltage and 6kV impulse withstand, so it's fine for most installations, and the mechanical life is 20,000 operations with 10,000 electrical cycles (usually plenty for a fixed installation). Physical width runs 18mm per pole, so a 4P unit sits at 72mm or 90mm depending on the variant you order.
We've been supplying these for years, so what you get is consistent — CE and CCC certified, and we usually have stock on common ratings (16A, 20A, 32A) but confirm lead time for teh 1A or 63A ends. Bulk pricing works out better if you're ordering 500 units or so per model.
One thing buyers don't always think to ask: the arc-extinguishing chamber is air medium, which is pretty standard for this class, but it does mean the unit is slightly taller than some compact designs — just check your enclosure depth before ordering.
You can get it in 1P, 2P, 3P, or 4P versions. The 2-pole model is standard, but we can supply any configuration you need.
Typically 15-20 working days for standard orders. If you need a faster turnaround, let us know the quantity and we can check availability.
Yes, we include both CE and CCC certification copies with every order. They're compliant with international standards.
The 1-pole unit is 18mm wide. For 2P it's 36mm, 3P is 72mm, and 4P is 90mm. All fit standard DIN rail mounting.
We offer B, C, and D curves as standard, and current ratings from 1A to 63A. Custom markings or packaging are possible for larger MOQs, but the electrical specs are fixed.
