Surge Protection Devices
SPD2 1P+0 SERIES
Class II/Type 2/Type 1 CA Pluggable Single-Pole
Pluggable RC
Connector
Description
Surge protection devices (SPDs) provide equipment protection
from transient overvoltage events lasting micro-seconds. By
limiting the overvoltage to the equipment during these events,
costly damage and downtime can be mitigated.
Visual Life
Indicator
The surge protection devices for the 1+0 configuration are
available for 60 V to 600 V nominal voltage sub-distribution
board applications.
