CITEL protects all electronic and electric equipment from lightning strikes and electrical transients caused by lightning and switching transients and electromagnetic interferences.

For this, CITEL manufactures two complementary products lines:

Gas Discharge Tubes (GDTs)

are the basic passive components used to protect telephone exchanges and equipments from voltage surges; the GDT is a small hi-tech component (less than 1 cm) and they are generally installed on telephone networks by telecommunication operator.

We are the only ones to manufacture our own GDT that we integrate into our protection moudules.

CITEL products, thanks to many patents, are homologated by a lot of international groups.

Surge Protection Devices (SPDs)

are units combining several protection components. The may be used by the installer or by the end customer.

They are designed to be incorporated in an installation to protect all electric, electronic and data-processing equipment from transient overvoltages.

The CITEL range: wide and complete

Whether standard or custom solutions, we cover all our clients needs. This ambition guides our daily activities.

Adapting to local markets specific needs, risk levels and applications, we offer protection for low voltage installations, communication networks, photovotaic systems as well as LED lighting.

The millions of SPD’s made and sold each year are proof positive of the high-quality standards, consistency and reliability of our products for our clients and partners around the world
