The main technical parameters of the motor protector are revealed
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 ≤0.2s.
(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.
