Manual transfer switch HTS

intelligentautomaticpanel-mount

Overview
The HTS residential Automatic Transfer Switch (ATS) integrates the switching mechanism and a microcontroller-based controller into a single compact unit. Its height matches BH‑type MCCBs for direct fit into household distribution panels. Available configurations: 2P 80A 110V, 2P 80A 220V, 3P 80A 220V (single-phase 3‑wire) and 3P 80A 220V (three-phase 3‑wire). During transfer an intermediate “both sources OFF” pause provides arc extinction time, allowing safe on-load switching at rated voltage and current. Typical applications include residential buildings, telecom base stations and small renewable-energy systems.
