Product Category: Distribution Box

This product is a 380V‑415V wide‑voltage ATS automatic transfer distribution box specially designed for three‑phase low‑voltage power distribution systems. Compatible with AC 380V‑415V three‑phase four‑wire distribution systems, it delivers automatic transfer between two power sources and accommodates power grid systems of varying voltage levels. Its ingress‑protection rating is IP30 (IP55 available for custom order). Compact and easy‑to‑install, it is internally fitted with ATS switch, circuit breakers, metering instruments and other components. Multi‑protection functions including overload, short‑circuit and earth‑leakage are integrated to provide reliable dual‑power‑supply backup for small‑size critical loads.

① Wide‑voltage design suits three‑phase distribution systems from AC 380V to 415V. It complies with grid‑voltage standards across different countries and regions and meets power‑distribution requirements for imported equipment.

② Compact cabinet‑style construction enables straightforward installation. It can be wall‑mounted or placed inside equipment rooms, making it ideal for dual‑power‑supply retrofits of small‑scale machinery.

③ Multiple transfer modes are selectable. Auto‑return or non‑auto‑return modes can be configured according to load characteristics for diverse power‑supply applications.

④ Comprehensive protection features continuously monitor voltage conditions of both incoming power sources and trigger automatic transfer upon anomalies. Overload, short‑circuit and earth‑leakage protection safeguard connected load equipment.

⑤ Customizable configuration. Rated current, circuit quantity and auxiliary functions can be adjusted to fit various operating‑site requirements.

Power distribution supporting imported equipment, dual‑power supply for small‑industrial machinery, power supply for office equipment, emergency power for small retail premises, power distribution for compact medical devices, power supply for communication terminal units, fire emergency‑lighting systems, power distribution for surveillance equipment and other applications requiring wide‑voltage‑range dual‑power‑supply backup.

Q1: Which voltage systems is the 380V‑415V ATS distribution box compatible with?
A: This product works with AC 380V‑415V three‑phase four‑wire distribution systems. It fits domestic 380V power grids as well as overseas 400V and 415V grid systems, and is well‑suited for supporting imported equipment.

Q2: What is the maximum achievable rated current?
A: The standard model reaches 250A maximum rated current. Higher‑current versions up to 630A can be custom‑manufactured on request.

Q3: Does manual transfer mode exist?
A: Yes. Both automatic and manual modes are available. Manual emergency operation can be activated in case of automatic‑mode failure. Mechanical and electrical dual interlocks are implemented to prevent incorrect operation.
