The Schneider GV3L65 is a 65 A, 3-pole motor circuit breaker from the TeSys Deca range. It provides magnetic-only overload protection (fixed at 910 A) and switches motor loads up to 55 kW at 690 V. The part carries a full AC-3 utilisation category for motor switching, rated for 50,000 electrical cycles at rated current. That translates to reliable daily starts in fan, pump, or compressor duty without premature contact wear.
Rated IP20 with the handle installed, so it stays protected against finger contact in a panel enclosure. The rotary handle makes manual isolation straightforward. Operating altitude to 3000 m without derating, and storage temperature from -40 to 80 °C — rated for the nacelle environment where seasonal extremes hit. Mechanical durability is 50,000 cycles, and it withstands vibration to 4 Gn over 5–300 Hz — tough enough for turbine tower shake.
Listed to EN/IEC 60947-2 and 60947-4-1, plus UL 60947-4-1 and CSA C22.2 No 60947-4-1. It also meets IEC/EN 60335-1 (clause 30.2) for glow-wire ignition resistance. Tested to fire resistance at 960 °C. If your panel requires UL/CSA marks for motor protection, this breaker carries them.
