The GPS8-13 is a 1-MODULE DIN rail-mounted low-voltage protector designed specifically for household equipment. Its core functions include triple protection against overvoltage, undervoltage, and overcurrent. It operates at a rated supply voltage of AC220V (L-N) with a frequency range of 45~65Hz, a working voltage range of 80V~400V, and optional rated operating currents of 32A/40A/50A/63A/80A. Featuring true RMS measurement technology (measurement error ≤1%) and an L/N dual-contact power-off design, the protection thresholds are customizable (overvoltage 230V~300V, undervoltage 140V~210V, overcurrent 1A~corresponding rated value). The action delays are 0.1s~10s (for over/undervoltage) and 2s~600s (for overcurrent), with a reset time of 2s~900s (default 30s). It is equipped with dual digital displays and an LED fault indicator, with a protection rating of IP40 on the front panel and IP20 on the terminals. Dimensions are 82×36×68mm, weighing 135g. Installation must be performed by a qualified electrician, and the upstream MCB should be disconnected during maintenance.
