The Schneider Electric GV4L03N is a 3-pole motor circuit breaker from the TeSys Deca range, rated at 3.5 A continuous current and designed for motor protection per IEC 60947-4-1. The 3.5 A rating means this breaker is sized for small motor loads — think fractional-horsepower pumps, fans, or conveyors on 400 V three-phase systems where the motor full-load current sits at or below that figure. The magnetic trip range of 21...49 A handles the inrush without nuisance tripping.
Breaking capacity and fault handling
Breaking capacity hits 100 kA Icu at 240 V AC and 50 kA at 415 V AC per IEC 60947-2. The breaker's role is protection and isolation, rated for 40,000 electrical cycles under AC-3 conditions at 440 V.
The EverLink BTR connectors on top accept 1.5...70 mm² solid or 1.5...50 mm² flexible cable; the bottom terminals go up to 95 mm² solid. Tightening torque is 9 N·m for the larger cable range, 5 N·m for the smaller — a torque wrench is worth using here to avoid terminal heating under continuous load. IP40 front face with IK07 impact resistance suits it for enclosed panel mounting where occasional tool drops or panel-door knocks are expected.
Compliance documentation covers EN/IEC 60947-2 and 60947-4-1, with a fire-resistance rating of 960 °C per IEC 60695-2-11 and climatic withstand per IACS for marine environments. The grey RAL 7016 housing is standard for the Deca range.
