Introduction

Surge Protective Devices (SPDs) protect equipment from transient overvoltage events lasting microseconds. By clamping overvoltages to within acceptable levels during these events, costly damage and downtime can be reduced. SPDs for branch distribution panel applications with nominal voltages from 60V to 600V.
