Type 1 surge protective devices are designed to discharge high current surges without any
destruction of the installation. These surge protective devices are characterized by their 5
capacity to withstand impulse current with 10/350 µs wave form which simulate natural
lightning current.
Type 1 SPDs can be installed at the entrance in the main switch board for a global protection
of the electrical installation.
