Low-voltage electrical manufacturer identified in the official NXB-63 declaration. This profile researches Zhejiang CHINT Electrics, a distinct legal entity from the original CHINT Group lead. NXB-63 miniature and NXB-125 moulded-case breaker records below preserve their separate catalogue classifications and rating conditions.

NXB-63 miniature circuit breaker
Australian regional table gives 1–63 A and B/C/D curves. Higher breaking-capacity values have a narrow pole/voltage scope; do not apply them to every variant or to NXB-63H.
Company publication ↗NXB-125 moulded-case circuit breaker
The AC catalogue lists six current variants. Regional HTML has a shorter list, so 70 A and 90 A availability must be confirmed rather than inferred.

Manufacturing & testing
The dated company ESG report describes low-voltage product development, manufacturing and sales and the relationship to CHINT Group. Historical disclosures do not establish current capacity or every product’s manufacturing location.
Company overview material describes digital miniature-breaker, contactor and relay workshops and production/quality monitoring. These are company descriptions; no plant visit, current equipment inventory or independent factory audit is claimed.
The address in the NXB-63 declaration identifies its named manufacturer. Confirm the actual producing site, model order code, routine tests and current market documentation for the order; do not extend one declaration to the whole brand.
Technical & quality documents
These are public-document leads. Current certificate validity and product applicability have not been independently established.
NXB-63 exact configuration
Regional table separates pole/voltage combinations and conditional breaking capacities.
Before approval
Obtain the exact model/order code, pole scheme, voltage, trip curve, approved short-circuit rating and current destination documents.
NXB-125 AC catalogue
The linked catalogue lists AC current and pole/voltage options separately from its DC table.
Before approval
Confirm the active revision and exact current variant. Do not combine AC ratings with DC pole/voltage limits.
Current quality and market evidence
The reviewed NXB-63 declaration is dated 2024; no present model certification is independently established.
Before approval
Match the current declaration/test certificate, manufacturer, plant and scope to the complete ordered product.
What to confirm before an order
Buyer guidance from Honyawn Atlas — not a statement of the manufacturer’s commercial terms.
Electrical system
Provide AC/DC, frequency, system voltage, pole scheme and installation conditions.
Protection selection
Have the responsible engineer specify load current, trip characteristic and fault-current coordination for the exact model.
Configuration and acceptance
Confirm order code, dimensions, mounting, terminals, accessories, current documents and routine inspection records.
Supply
Agree legal seller, producing site, quantity, MOQ, price, lead time, packaging, traceability and warranty.
Have a specification ready?
Include the drawing or standard, quantity per size and delivery destination. Select quotation, samples or technical documents in the request form.
