Circuit Protection

DZ47-63 2P Miniature Circuit Breaker 400V

DZ47-63 2P MCB manufactured by Walax to the classic DZ47 footprint, widely used across Africa and Asia. Double-pole protection for 230V split-phase circuits and small commercial sub-panels requiring simultaneous isolation of line and neutral.

Classic DZ47 Footprint

Direct drop-in replacement for existing DZ47 installations — same module width, same DIN-rail geometry, same terminal layout.

Simultaneous L+N Trip

Both poles open together on fault or manual operation — safer isolation for 230V split-phase residential circuits.

High kA Capacity

6kA breaking capacity at 400V covers the short-circuit levels encountered in typical residential and small-commercial distribution boards.

FAQ

Frequently Asked Questions

Is this MCB a direct replacement for DZ47?

Yes — the footprint, terminal layout and module width match the classic DZ47 standard, allowing direct swap into existing boards without re-wiring.

What's the difference between 1P+N and 2P?

1P+N protects only the line conductor (neutral shares the same module). 2P protects both line and neutral with separate physical poles that trip simultaneously. 2P is required by many installation codes for residential sub-circuits.

Do you supply higher kA ratings?

Yes — 10kA versions are available for installations with higher prospective short-circuit levels. Contact us with your specifications.

What certifications do you carry?

IEC 60898-1 type test reports and CE documentation come with every shipment. SONCAP (Nigeria), PVOC (Kenya, Tanzania) and other country-specific certifications are available on request.
