Company profile

A manufacturing base since 2002.

Backed by a manufacturing base established in 2002 in Liushi, Wenzhou — a recognised centre of China's low-voltage electrical industry — we develop and produce distribution boxes, circuit breakers, isolators, surge protection devices and fuses. These products protect electrical systems from overload and power disturbance to keep installations running safely and reliably.

Our quality management is backed by ISO 9001, with products certified to CB, SEMKO, CE, UKCA and TÜV as applicable — supporting distributors, panel builders and OEM programmes across Europe and international markets.
