The Schneider Electric GV4LE12N6 is a TeSys Deca motor circuit breaker — a 3-pole, 12.5 A rated unit (In) from the GV4 family. It's built for motor protection on three-phase loads up to 690 V AC, with a magnetic-electronic trip unit that handles both short-circuit and overload conditions. That kind of headroom means it clears a fault without the breaker welding shut, even on a stiff industrial service. Rated for continuous duty per IEC 60947-4-1, and suitable for isolation per IEC 60947-1 — you can lock it out as a visible disconnect.
The 12.5 A In is the continuous current; you size upstream protection and cable to this. Motor power depends on voltage: at 400 V it covers up to 5.5 kW, at 690 V up to 11 kW. The magnetic trip range is 75–175 A, so it rides out motor inrush without nuisance tripping on direct-on-line starts. Duty category AC-3 per IEC 60947-4-1 confirms it's rated for switching squirrel-cage motors — starting and disconnecting under load. Pollution degree 3 means it's fine in a typical industrial panel where some conductive dust is present. IP40 body keeps out tools and fingers but not water; mount it inside a cabinet, not out on the washdown floor. IK07 impact rating means it'll survive a dropped screwdriver against the enclosure.
Deployment context
Connection pitch is 27 mm without spreaders, 35 mm with — lines up with standard busbar systems. Terminals accept ring lugs on cable from 1.5 to 95 mm²; torque the main power lugs to 9 N·m. The toggle control gives a clear on/off visual, and the grey RAL 7016 body blends into a modern panel layout. Operates in any position, altitude up to 5000 m, ambient storage from -50 to 85 °C.
