The GPS8-10 is a DIN rail-mounted voltage and current protector with WiFi-enabled smart control, specifically designed for household appliances. Its core functions include four levels of protection: overvoltage, undervoltage, overcurrent, and leakage current. It operates at a rated supply voltage of AC220V (L-N) with a frequency range of 45~65Hz, and a working voltage range of 80V~400V. The rated operating current options are 32A/40A/50A/63A/80A. Featuring a dedicated metering chip (measurement error ≤1%), it supports multi-parameter monitoring of voltage, current, power, and electricity consumption. Equipped with a large color screen and LED fault indicators, the leakage current protection threshold ranges from 10mA to 400mA (default 30mA), with 1~20 automatic reclosing attempts (default 3 times). Remote control, parameter settings, and fault alerts can be managed via a mobile app. The protection rating is IP40 for the front panel and IP20 for the terminals, with dimensions of 82×54×68mm and a weight of 205g. Installation must be performed by a qualified electrician, and the upstream MCB must be disconnected during maintenance.
