V-CHECK 4R

V-CHECK 4R is the range of combined transient and power frequency overvoltage protection devices (SPD+POP), intended for actuation on undervoltage release of a moulded case circuit breaker (MCCB not included), Type 2 / Class II, 40 kA (8/20 μs) surges, 4 pole (3P+N), for 230 V with test button for POP.

  • With V-CHECK 4R 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 facilities and on-site panels.
