Surge Protection Devices
SPD2 1P+1 SERIES
Class II/Type 2/Type 1 CA Pluggable Multi-Pole
Description
Surge protection devices (SPDs) provide equipment protection
from overvoltage events lasting micro-seconds. By limiting
the overvoltage to the equipment during these events, costly
equipment damage and downtime can be mitigated.

Indicator
The surge protection devices for the 1+1 configuration are
available for 60 V to 277 V nominal voltage sub-distribution
board applications.
