Type 1+2 AC Surge Protection Devices

These are very compact SPDs which protect both from overvoltage surges due to direct lightning strikes (10/350 µs waveform) as well as indirect lightning strikes and switching surges (8/20 µs waveform). They are an integrated solution, equivalent to an automatically coordinated Type 1 and Type 2 SPDs. They are used as the first step of protection in incoming power supply panels and areas with exposure to the atmosphere, where installations are usually provided with an external lightning protection system.

Configuration

SPN, TPN

Specification

IEC 61643-11: 2011, EN 61643-11: 2012

Features

• Tested and approved by TUV.
• High Discharge Current (Imax 50 kA (L – N) 70 kA (N – E)).
• Compact Size Integrated Type-1 & Type-2 protection in small module width (Ideal in all reduced-size spaces).
• Better Protection due to reduced Up(Voltage protection level 1.5 kV).
• Both Common & DIfferential Mode Protection.
