What the 115 A rating means for your motor branch
The GV4LE115B6 is a 3-pole motor circuit breaker from the TeSys GV4 family, rated 115 A continuous. That 115 A is the full-load current it carries without tripping — sized for a 37 kW motor at 400 V or up to 110 kW at 690 V, depending on the line voltage. The magnetic-electronic trip unit gives you adjustable magnetic pickup between 480 and 1120 A, so it handles inrush without nuisance trips while still clearing a bolted fault. Breaking capacity hits 50 kA Icu at 240 V, 25 kA at 415 V, and 10 kA at 500 V — all per IEC 60947-2.
Connection pitch is 27 mm without spreaders, 35 mm with them, so you can land 16 to 95 mm² cable at 9 N·m on the lugs. The IP40 enclosure keeps dust out but isn't washdown-rated; it's meant for a clean, dry cabinet. That saves a separate isolator in the panel.
Durability and environmental tolerance
Mechanical durability is 40,000 cycles; electrical durability is 10,000 cycles at AC-3 at 440 V at half rated current, or 5,000 cycles at full rated current. That's typical for a motor-circuit breaker in a production line — you'll get years of daily starts before the contacts wear. Operating altitude goes to 5000 m, and it works in any mounting position. Storage temperature range is -50 to 85 °C, so it survives warehouse extremes. Climatic withstand per IACS means it handles marine-environment humidity cycles.
