Product Features<\/h2>\n

\u25a0\u00a0Wide Application Range<\/p>\n

Suitable for single-phase AC 230V, 50Hz systems with rated current up to\u00a080A,protecting\u00a0against neutral line faults.<\/p>\n

\u25a0\u00a0Automatic Recovery Function<\/p>\n

Automatically reconnects circuit within specified time (30s\u00b110s) when\u00a0voltage returns to normal,\u00a0ensuring continuous operation without manual\u00a0intervention.<\/p>\n

\u25a0\u00a0Intelligent Voltage Protection<\/p>\n

Utilizes high-speed micro low-power processor and magic holding relay to\u00a0quickly cut off power\u00a0during over\/undervoltage conditions, preventing\u00a0damage to terminal equipment.<\/p>\n
