Interruttore automatico del motore GV3P80

GV3P80 is a 3‑pole thermal‑magnetic motor circuit breaker from Schneider Electric TeSys GV3 series. It has an adjustment current range of 70–80A, suitable for 45kW (400V) / 55kW (690V) three‑phase motors. It integrates triple protection (sovraccarico, short‑circuit, mancanza di fase) and isolation function, serving as a core protection component in industrial motor circuits.

Suggerimenti per la selezione

1. Select adjustment range at 1.1–1.25 × motor rated current
2. Confirm breaking capacity meets system short‑circuit current requirements
3. For isolation function, prefer models with certified isolation
4. For limited wiring space, choose EverLink terminal models to reduce faults
