GPS8-02 is a 1-module DIN rail mounted over-voltage and over-current protector designed specifically for home devices. It has a rated supply voltage of AC220V (L-N), a frequency of 45~65Hz, and a rated operating current of 32A/40A/50A/63A/80A. Its core functions include triple protection for overvoltage (230V~300V, factory default 275V), undervoltage (145V~210V, factory default 175V), and over-current (1A~corresponding to rated current). The over-voltage/undervoltage action delay is 0.5s, the over-current action delay is 5s, the power on delay is 2s, and the reset time is 2s~900s (default 30s). The measurement error is ≤ 1%, and the protection level is front panel IP40/terminal IP40/terminal IP40. 20, size 82 × 36 × 68mm, weight 135g, supports digital display of voltage/current/fault status and LED indication, automatically resets after fault, must be installed by qualified electricians, and electrical waste must be disposed of in accordance with WEEE regulations.
