The 50 A rating means it directly protects a motor drawing that full-load current — no external overload relay needed. ## Breaking capacity — what it handles in a fault Breaking capacity is 50 kA Icu at 240 V AC, dropping to 25 kA at 415 V and 10 kA at 500 V. At 400 V nominal, the 25 kA Icu covers most industrial distribution boards. ## Motor power coverage — which motors it fits The GV4LE50B6 covers a wide motor power band depending on line voltage: 11 kW at 400 V, 18.5 kW at 500 V, and up to 45 kW at 690 V. That spread means one part number serves motors across different supply voltages — useful for a plant with mixed-voltage zones or export machines. Dimensions are 155 mm high, 81 mm wide, 116 mm deep — a compact 3-pole footprint that fits standard DIN-rail or panel-mount layouts. Operating altitude up to 5000 m, any mounting position. Mechanical durability is 40,000 cycles; electrical durability is 20,000 cycles at AC-3, 440 V at half rated current, and 10,000 cycles at full rated current. Maximum operating rate is 25 cycles per hour — fine for a motor starting a few times per shift, not for high-speed jogging. Power dissipation is 6.1 W per pole, so three poles total 18.3 W of heat inside the enclosure — account for that in thermal calculations. Certified to EN/IEC 60947-4-1 (motor starters) and EN/IEC 60947-2 (circuit breakers). Climatic withstand conforms to IACS for marine environments. Fire resistance at 960 °C per IEC 60695-2-11. Rated insulation voltage 800 V, operational voltage 690 V.","metaTitle":"Schneider Electric GV4LE50B6 TeSys GV4 Motor Circuit Breaker","metaDescription":"Schneider Electric GV4LE50B6 motor circuit breaker, 50 A rated current, 3-pole, TeSys GV4 series.
