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.
Class II / Type 2 Surge Protection Device (SPD)
Prosurge V50, DS50, DT50 series surge protective devices (SPDs) are designed to protect electric installations and sensitive equipment against indirect surges and ensuring a low protection level (Up). It is characterized by its capacity to safely discharge current with 8/20 µs waveform.
With built in PROSURGE high energy MOV and GDT, this SPD ensures remarkable lightning current discharge capacity up Imax 50kA 8/20. The unique design of thermal protection provides quick thermal response and secure disconnection.
This SPD series feature Prosurge’s global patented fail-safe and self-protected technology, offering quick thermal response and perfect cut-off function and providing fast and reliable protection for various power supply systems.
Class III / Type 3 Surge Protection Device (SPD)
Type 3 Surge Protection Device (SPD) is designed for low-voltage power supply system protection against surges at the boundaries from lightning protection zone 2-3 and higher.
They shall be installed as close as possible from the sensitive equipement to protect. Tested with a 1,2/50 – 8/20 current combination wave generator, they ensure a very low protection level voltage value.
- Comply with IEC 61643-11
- Pluggable design, easy replaced without any tools.
- High Discharge Capacity with 8/20 us waveform, Imax 10kA
- High reliability due to thermal disconnection device
- Fast response
- Visual status indication and remote signal contact available
