GV3L25 is the 25 A three-pole motor circuit breaker in the TeSys Deca range. Magnetic-only trip unit fires at 350 A, which keeps it out of nuisance trips on moderate inrush while still clearing short circuits fast. Breaking capacity at 400/415 V is 100 kA Icu — that’s enough to sit on a high-fault bus without an upstream fuse eating panel space. Rated for AC-3 duty, meaning it’s sized for squirrel-cage motor starting. Electrical durability is 50,000 cycles at full load in AC-3, which matches the mechanical rating — a good indicator that the switchgear isn’t overrated for frequent cycling.
Approved to EN/IEC 60947-2, -4-1, UL 60947-4-1, and CSA C22.2 No 60947-4-1. Also passes glow-wire at 960 °C per IEC 60695-2-11 and the appliance standard 60335-1 clause 30.2, which covers motor protection in HVAC equipment.
IP20 finger-safe terminals; torque terminals to 5 N·m. Accepts horizontal or vertical orientation. Operating altitude rated to 3000 m without derating — keep that in mind if the panel goes into a high-elevation plant.
