What This Range Is For

Miniature circuit breakers for AC and DC final circuits in residential, commercial and industrial applications. The range includes AC MCBs to GB10963.1 and IEC60898-1, and DC-rated versions for solar and control circuits, all built on a shared DIN-rail footprint so a buyer can manage one BOM for both AC and DC protection.

Who Buys This Range

  • Electrical wholesalers stocking final-circuit protection by the box
  • Panel builders and switchgear assemblers filling outgoing ways in distribution boards
  • Solar installers protecting DC strings and combiner boxes
  • Industrial contractors installing high-current load protection in large-scale construction
  • OEM machine builders integrating protection into control cabinets

Problems It Solves

  • AC MCBs cannot be used on DC circuits, requiring separate inventory for solar and control applications
  • Lack of DC-rated breakers leads to unsafe or non-compliant installations in solar and battery systems
  • Different pole widths and footprints across brands complicate panel assembly and spare part stocking
  • Panel builders need a single MCB series that supports both conventional and future smart upgrades
  • High-current industrial circuits require breakers with no derating under continuous load

Where It Is Used

  • Lighting and socket circuits in residential consumer units using AC MCBs
  • Machine control cabinets needing compact final-circuit protection with Type C tripping
  • Solar PV string and combiner box protection on the DC side with DC-rated DZ47Z-63
  • High-current industrial circuits in large-scale construction using HT47-100 series
  • Control circuits in industrial panels requiring direct current protection with DZ47Z-63 DC
Advantages

What Separates This Range

  • AC and DC miniature breakers built on the same DIN-rail footprint for unified inventory
  • Type C trip curve suitable for general lighting, socket and moderately inductive loads
  • Pole options from 1P to 4P within one series, including HT47-100 for high-current applications
  • No derating under continuous load, suitable for high-current industrial use
  • Sealable handle or padlock bracket available for safety in high-risk environments

MCB RCBO and AFDD What Each Device Actually Protects

Three DIN devices that look alike protect against three different faults. Getting the selection wrong leaves a real risk uncovered.

The protection is the same. The difference between the three smart ranges is how the device reaches the person who wants to switch it.

Why a DC Circuit Needs a DC Rated Breaker

An AC breaker fitted to a solar string is one of the most common sourcing mistakes on the DC side and the reason the DZ47Z-63 series exists.

FAQ

Mini Circuit Breaker(MCB) Questions

What trip curve do these breakers use

Type C, which suits general lighting, socket and moderately inductive loads.

Can an AC MCB be used on a DC circuit

No. Use the DC-rated DZ47Z-63 series, designed for DC 12V to DC 1000V with a 4.5kA ultimate breaking capacity.

Which standards are these built to

GB10963.1 and IEC60898-1 are the standards stated for this range.

What pole configurations are available

1P, 2P, 3P and 4P versions are available within the series.

Do you supply under our own brand

Yes. We run ODM projects and print buyer branding on the housing and packaging.

What are the minimum order quantity and lead time

They depend on ratings and branding. Email [email protected] with your model list and quantities.
