GK3EF80 TeSys GV3 magnetic motor-protection circuit breaker: technical facts and site checks
GK3EF80 is the exact designation used for this TeSys GV3 magnetic motor-protection circuit breaker entry. The picture is a shared Schneider-category reference collage, not an exact photograph of GK3EF80. Use the confirmed details below as the starting point for enquiry; the installed label and current manufacturer document govern final selection.

Site information to collect
Before ordering GK3EF80, write down the existing equipment tag, location and duty. Check coordination with the contactor and overload device at the available fault level. Capture a legible photograph of the complete GK3EF80 marking so that voltage, option suffix and revision can be compared with the quotation.
Check the mating equipment around GK3EF80: 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 GK3EF80.
Quotation worksheet
- Complete GK3EF80 designation and quantity
- Condition, revision and applicable manufacturer documentation
- Included accessories, exclusions and delivery region
- Any proposed substitution identified separately for approval
For GK3EF80, 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 If the original GK3EF80 is obsolete, confirm availability and obtain an engineering-reviewed migration path rather than assuming a current series is a direct swap.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 GK3EF80. 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 GK3EF80 is removed.
The acceptance test for GK3EF80 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 GK3EF80 is correctly configured.
Similar-looking designations
No additional unassigned GK3-pattern code is indexed with GK3EF80. A different complete designation still requires its own technical check.
Release decision
Approve GK3EF80 for procurement only after the exact model, documented product role, site connections and supplier offer agree. Keep GK3EF80 on the purchase and receiving records. If a substitute is proposed, document the differences and obtain approval before fitting it.
