DIN Rail Surge Protection
Devices, SPD
Prosurge’s SP series surge arrester is UL1449-4th addition approved SPD especially designed for low-voltage
power supply system surge protection at the boundaries from lightning protection zone 0B-2 and higher. It is a DIN-rail
designed surge protective device featuring Prosurge’s global patented design of thermally protected MOV with special
arc-extinguish device, providing fast and reliable protection for various power supply systems. Modules feature a visual
fault indicator and an optional remote alarm contact is available to monitor the operating status of the surge protector
by signaling an alarm. The SP series has a very high short circuit current rating of 200kArms, which eliminates the
requirement for additional overcurrent protection devices.
