Combined protector against permanent (POP) and Type 2 transient overvoltages (SPD) with Imax 40 kA. V-CHECK 4RC range is suitable for protecting tertiary/commercial low-voltage installations against overvoltages.
* With V-CHECK 4RC the installation is protected against transient voltage spikes as well as voltage increases which last for an indefinite period. Typically, the first are associated with the phenomenon of lightning and the second with bad connections or faulty neutral in 3-phase installations.
* High surge discharge capacity.
* When it acts on the contactor (not supplied) the resulting system will provide automatic reclosure capability.
* Ideal for street lighting systems.
