Product Category: Automatic Transfer Switch

This ATS automatic transfer switchgear is designed for 220 V low‑voltage distribution systems. Compatible with AC 220 V single‑phase / three‑phase power distribution systems, it performs automatic transfer between two 220 V power sources, enabling intelligent switching between mains‑to‑mains and mains‑to‑backup power supplies. Compact and easy‑to‑install, it has IP30 protection class (IP55 available upon customization). Equipped with built‑in ATS switch, circuit breakers and protective components, it delivers multi‑layer protection including over‑voltage, under‑voltage, phase loss, overload, short‑circuit and earth‑leakage protection, providing reliable dual‑power supply assurance for small critical loads powered by 220 V.

Q1: What applications are suitable for this 220 V ATS switchgear?

A: Designed for 220 V low‑voltage distribution systems, this unit provides dual‑power backup for critical equipment in homes, small shops, offices and small medical facilities. It automatically switches to backup power during mains failure to keep equipment running continuously.

Q2: What is the maximum rated current available?

A: The standard version reaches 250 A maximum rated current. Higher current ratings can be custom‑made to satisfy 220 V loads of different power levels.

Q3: Does manual transfer mode get supported?

A: Yes. Both automatic and manual transfer modes are available. Manual mode can be activated when automatic mode malfunctions for emergency manual operation. Dual mechanical and electrical interlocks are adopted to prevent mis‑operation.
