Combined protector against permanent (POP) and Type 2 transient overvoltages (SPD) with Imax 40 kA. V‑CHECK 4RPT range is a solution with operation on shunt or undervoltage coils, designed to protect low-voltage installations against permanent and transient overvoltages.
* With V-CHECK 4RPT 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.
* Ideal for industrial and commercial installations.
