Manufacturing & testing
The contact page distinguishes Shanghai headquarters and the Hangzhou Bay factory in Haiyan. Obtain the legal producing entity and site for the chosen order.
The official sustainability page describes Shanghai and Hangzhou Bay test facilities, including company statements about CNAS, UL witness testing and TÜV cooperation. Those descriptions do not establish current certificate validity or scope.
Manufacturer descriptions include factory assembly and logistics. Exact model-level production routes, routine tests and lot records were not established in the reviewed product range.
Technical & quality documents
These are public-document leads. Current certificate validity and product applicability have not been independently established.
Current model datasheet
The official range provides series current and voltage options.
Before approval
Request exact order code, poles, trip characteristic, terminal capacity, dimensions, mounting and approved AC/DC rating combinations.
Breaking capacity and coordination
A family or marketing rating does not define performance at every voltage or system configuration.
Before approval
Obtain selected-voltage interrupting ratings, test standard and edition, coordination/selectivity data and installation instructions.
Market and factory documents
The company describes testing resources; model-specific approvals were not validated here.
Before approval
Check the exact model, applicable standard, certificate/listing number, current status and producing site for the destination market.
What to confirm before an order
Buyer guidance from Honyawn Atlas — not a statement of the manufacturer’s commercial terms.
Electrical system
State AC or DC, voltage, frequency, earthing arrangement and available fault current.
Exact configuration
Specify poles, rated current, trip curve, mounting, terminals and accessories.
Acceptance documents
Request current model datasheet, coordination data, installation instructions, market approvals and routine-test records.
Supply requirements
Confirm seller and plant, quantity, MOQ, price, samples, lead time and delivery destination.
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.
