Most RFQs we receive from new importers list a part number copied from another brand. That is not enough to quote. A Yueqing source factory needs five fields: poles, rated current, trip curve, breaking capacity, and the language on the rating plate and carton.

Example that quotes the same day: 4P 32 A C-curve 10 kA, English/Spanish plate, white PA66 housing, 1,000 pcs, FOB Ningbo. Example that waits: “MCB like Schneider, best price, 20 ft.”

If you need a private-label laser window, say so in the first message. A housing colour that is not already in the family adds a mould change — we will tell you on day one, not after the deposit. Drawings can follow on WhatsApp; they should not replace the five fields.
