Description

SGV2-II-32 and SGV3-II-80 adopt two frame sizes to cover complete current specifications from 0.1A to 80A, matching three-phase motors of 0.37kW up to 63kW under 230V–690V power supply. Each specification features adjustable thermal setting and fixed instantaneous short-circuit tripping, with graded Icu/Ics breaking capacity at 400V and 690V for reliable fault cutoff.

It has independent mechanical and electrical life parameters for each frame and standard motor protection tripping curves to avoid motor burnout. Stable performance under 90% maximum humidity and 2000m altitude, standard DIN rail mounting. Widely used as standalone protection for machine tools, water pumps and general industrial three-phase motors.
