It combines magnetic and electronic trip technology to protect against short circuits and overloads, with a breaking capacity of 120 kA Icu at 240 V AC and 100 kA at 415 V AC per IEC 60947-2. The 80 A rating sets the motor full-load current threshold — wire it for a 37 kW motor at 400 V or up to 55 kW at 690 V. Rated for AC-3 duty per IEC 60947-4-1, this breaker handles the inrush of squirrel-cage motors during starting and switching. The magnetic trip range is 480–1120 A, adjustable to coordinate with motor starting characteristics. Continuous duty rated per IEC 60947-4-1 means it carries the 80 A load indefinitely without derating in a 40 °C ambient.
The GV4LE80S6 measures 155 mm high, 81 mm wide, and 116 mm deep — a compact 3-pole footprint for DIN-rail or screw-mount installation in a motor control center. Connection pitch is 27 mm without spreaders, 35 mm with them, accepting lugs or ring terminals up to 95 mm² cable at 9 N·m torque. IP40 front protection keeps out tools and fingers; IK07 impact rating handles panel-door knocks. Operates in any position at altitudes up to 5000 m, with storage from -50 to 85 °C. Fire resistance rated at 960 °C per IEC 60695-2-11.
Approvals include EN/IEC 60947-2 and 60947-4-1, with suitability for isolation per IEC 60947-1. Climatic withstand conforms to IACS for marine and humid environments. No UL listing is stated in the evidence, so verify for North American panel builds.
