Introduction

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