SURGE PROTECTION

Surge Protectors

DEHN, Hitachi, Novaris, and ABB are the prominent manufacturers of
surge protection devices, providing critical solutions for safeguarding
electrical and electronic systems against voltage surges.

DEHN’s surge protectors are characterised by a modular design that
enhances flexibility and maintenance. Employing advanced Metal-Oxide
Varistor (MOV) technology, they ensure swift responses to voltage surges
and offer comprehensive protection with Type 1, 2, and 3 classifications.

Hitachi Energy (formerly known as ABB Power Grids) and ABB surge
protectors boast high performance, compact designs suitable for
various applications, and thermally protected varistors to prevent
thermal runaway during extended overvoltage conditions. Known
for easy installation, compliance with IEC 60099-4, and versatile
applications.
