The Schneider GV3L80 is a TeSys Deca motor circuit breaker rated 80 A continuous, 3-pole, with a magnetic trip set to 1120 A. That 1120 A magnetic trip means it's not for wimpy loads—expect it to ride through the inrush of a 45 kW motor on 400 V and still clear a bolted fault clean. Rated isolation according to IEC 60947-1, so you can hang a lockout tag on the rotary handle and treat the downstream bus as de-energized. The 55 mm width keeps the footprint tight for a 3-pole 80 A device.
The GV3L80 carries approvals under EN/IEC 60947-2 and -4-1, plus UL 60947-4-1 and CSA C22.2 No 60947-4-1. It also meets glow-wire resistance at 960 °C per IEC 60695-2-11, and is listed for isolation and motor protection in appliance standards IEC/EN 60335-1 and -2-40. Nameplate says dark grey; the enclosure sits in a -20 to 60 °C operating range.
