V-CHECK 4R is a combined transient and power frequency overvoltage protection device (SPD+POP) designed to protect the installation from transient voltage spikes and voltage increases that lasts for an indefinite period. The first are associated with the phenomenon of lightning and the second with bad connections or faulty neutral in 3-phase installations. The unit provides high surge discharge capacity making it ideal for industrial facilities and on-site panels. The unit is to be used for actuation on undervoltage release of a moulded case circuit breaker (MCCB not included), Type 2 / Class II, 40 kA (8/20 ?s) surges, 4 pole (3P+N), for 230 V with test button for POP.
