Circuit Protection

MCB 1P-4P 63A DIN Rail Circuit Breaker 6kA

Walax universal-fit MCB family with 1P, 2P, 3P and 4P configurations on the same 18mm-per-pole footprint. Stock one frame, configure the pole count to match the circuit — simplifies distributor inventory while covering every sub-circuit in a residential or commercial distribution board.

Universal Frame

1P / 2P / 3P / 4P from the same product family — one distributor SKU, every pole count. Simplifies inventory and panel-building.

18mm Per-Pole Width

Compact DIN-rail footprint — a 12-way distribution board fits in the same panel space as competing brands.

B/C/D Trip Curves

Full calibration range on the same frame — covers residential (B), commercial (C), and motor (D) applications.

FAQ

Frequently Asked Questions

Can I order a mix of pole configurations in one shipment?

Yes — mixed-SKU containers are standard for our export wholesale customers. Specify the pole count and current rating for each position in the order.

Is the 4P version suitable for three-phase systems?

Yes — the 4P configuration is the standard for three-phase + neutral protection in TN-S and TT distribution systems.

What's the difference between this and your other MCB series?

This universal MCB family is designed for distributors and panel builders who want one product range covering all pole counts. The other series (DZ47, IC65, NXB) are targeted at specific market preferences.

Do you have a 10kA version?

Yes — 10kA versions of all pole configurations are available on request. The 10kA version adds a current-limiting design for higher prospective short-circuit levels.
