Surge arrester type 2 CITEL

DS40 Type 2 AC surge protectors are used mainly for primary protection of single and 3-phase networks at the main electrical panel.

This SPD is based on high energy varistor equipped with thermal disconnector and failure indicator.

The DS40 is available for a large range of AC voltages.

The DS40 is DIN rail compatible and is built with a plug-in module and a fixed base, which allows an easy and fast maintenance :


- Type 2 AC surge protector

- Discharge currents : In = 20 kA / Imax = 40 kA

- Pluggable module for each phase

- Remote signaling in option

- IEC 61643-11 and EN 61643-11 compliance
