The main technical parameters of the motor protector are revealed时间£º2023-09-29 Main technical parameters of motor protector: (1) Working voltage: AC three-phase 300 ~ 460V, 50Hz. (2) Overvoltage protection: 380 ~ 460V adjustable, delay about 0.5 ~ 5s adjustable. (3) Under voltage protection: 300 ~ 380V adjustable, delay about 1 ~ 10s adjustable. (4) Phase break and phase sequence protection: action time ¡Ü0.2s. (5) Protection contact capacity: AC220V5A (resistance). (6) Power consumption: < 3VA. (7) The undervoltage and overvoltage action characteristics of the protector are shown. Characteristic line 1 is single-phase over and under voltage characteristic line; Characteristic line 2 is a two-phase overvoltage and undervoltage characteristic line. Characteristic line 3 is the characteristic line of three-phase overvoltage and undervoltage. (8) Protector setting parameter overvoltage value - setting knob can set the maximum value (upper limit) of the allowed operating voltage of the protected object. Undervoltage value - The setting knob sets the minimum allowable operating voltage of the protected object (lower limit). Overvoltage delay - the time (s) to reach protector action when the operating voltage exceeds the set overvoltage value. Undercalendering - Time (s) to reach protector action when the operating voltage is below the set undervoltage value. |
