Compact Quick Sense protector monitors three-phase voltage and current, cutting supply within 0.1–30 s to shield motors and equipment. Dual working modes allow full 3-phase protection or independent single-phase settings for flexible industrial control. Adjustable thresholds cover over-voltage 230–300 V, under-voltage 140–210 V and over-current 0.5–63 A, with configurable recovery and delay timers. DIN-rail mount, 9 x 6.5 x 9 cm housing and 1 kg build make installation neat and durable.
