Schneider NG125N: field dossier for NG125N modular circuit breaker

NG125N is the exact designation used for this NG125N modular circuit breaker entry. The picture is a shared Schneider-category reference collage, not an exact photograph of NG125N. Use the confirmed details below as the starting point for enquiry; the installed label and current manufacturer document govern final selection.

Technical data and identification

Site information to collect

Before ordering NG125N, write down the existing equipment tag, location and duty. Check the actual circuit fault level and installed pole/rating combination. Capture a legible photograph of the complete NG125N marking so that voltage, option suffix and revision can be compared with the quotation.

Check the mating equipment around NG125N: supply and load wiring, mechanical mounting, protection, communications or software interface as appropriate. The table intentionally separates documented facts from values that depend on a complete configured variant. Never infer a missing rating from a shared image or from another model whose code merely resembles NG125N.

Quotation worksheet

For NG125N, ask the supplier to quote the exact reference and disclose any deviation. A suffix, pole count, communications port, certification or terminal style can change the installation even when the front appearance is similar. If the original NG125N is obsolete, confirm availability and obtain an engineering-reviewed migration path rather than assuming a current series is a direct swap.

Installation and commissioning record

Keep the isolation and safety procedure for the equipment that uses NG125N. Compare delivered markings, package condition and accessories with the approved order. Record hardware and firmware revisions where present; preserve settings and backups before an installed NG125N is removed.

The acceptance test for NG125N should match its actual duty: switching or trip performance, protective settings, measured values, motion direction, software connection or busway continuity as applicable. Use qualified personnel and the manufacturer's commissioning instructions. A passing visual inspection alone does not prove that NG125N is correctly configured.

Similar-looking designations

No additional unassigned NG125-pattern code is indexed with NG125N. A different complete designation still requires its own technical check.

Release decision

Approve NG125N for procurement only after the exact model, documented product role, site connections and supplier offer agree. Keep NG125N on the purchase and receiving records. If a substitute is proposed, document the differences and obtain approval before fitting it.
