Class I+ Class II / Type 1+ Type 2 Surge Protection Device (SPD)

Type 1 and Type 2 Surge Protection Devices (SPDs) are designed to discharge high current surges without any destruction of the installation. This surge protective device is characterized by its capacity to withstand impulse current with 10/350µs waveform which simulates direct impact coming from a natural lightning current. Prosurge 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.

Prosurge provides Class I + Class II, Type 1 SPD with different technology of spark gap technology, VT technology and MOV technology.
