OVR T1 1N 25-255 Surge Protective Device 2CTB815101R1500
To protect the systems against the transient overvoltage (lightning)
OVR type 1 + 2 is designed to discharge high current surges without any destruction of the installation.
This surge protective device is chararcterized by its capacity to withstand impulse current with 10/350 μs wave form
which simulate direct impact coming from a natural lightning current.
Type 1-type 2 SPDs are placed at the entrance point of the installation, in the main distribution board for a global protection of this installation.
T1 - T2
Imp : 25 kA
· Din The impulse current of 25kA per pole (10/350 μs wave) satisfies all requirements for overvoltage surge protection
· The early creation of the electric arc by its electronic ignition device reduces the protection level Up to an otimum value of 1,5kV
· OVR T1+2 SPDs contain a dedicated arc chamber for extinguishing the electrical arc following the discharge, they can open short circuits.
