EU Plug Voltage Protection Socket

A dedicated voltage protection socket built for safeguarding refrigerators against grid instability, featuring automatic cut-off, timed recovery, and real-time visual feedback. Dimensions: 17.5 × 8.5 × 8 cm; weight: ~450 g. Rated for 3680 W maximum load at AC 220 V, with precise voltage sensing between 170 V and 260 V. Made from robust plastic housing with flame-retardant properties, and fitted with an authentic EU plug suitable for Indonesia and similar markets. The built-in delay logic requires 5–6 minutes of stable voltage before restoring output — not just momentary return — ensuring true grid recovery before re-engagement. LED indicators communicate system status without ambiguity: yellow = voltage present and within acceptable band, awaiting delay completion; green = power actively supplied; red = protection engaged, zero output. The ON/OFF switch only accepts commands when voltage remains continuously within 175–260 V — guaranteeing all manual actions occur only under verified safe conditions. This unit is especially effective in households where refrigerators run 24/7 and cannot tolerate unexpected shutdowns or erratic restarts — common pain points in developing infrastructure zones where voltage regulation is inconsistent and maintenance intervals are long.
