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.
The surge protection devices for the 4+0 configuration are
available for 120 V to 480 V nominal voltage sub-distribution
board applications.
Features & Benefits
FEATURES BENEFITS
Capability to clamp and
withstand high-energy
transients
UL Recognized and
VDE-IEC compliant in
single part number
Interlocking tab
mechanism
No additional
overcurrent protection
devices required in
UL applications
Compact footprint
Visual life indicator
Pluggable modules
Thermal protection Eliminates catastrophic failure
IP20 protection rating Finger-safe design increases worker protection
Ensures low-residual voltage during high-energy
surge events and higher nominal discharge current
to prevent disruption, downtime, and degradation or
damage to equipment
One component can be utilized globally, reducing
inventory needs and simplifying allocation of parts
Secures module to withstand vibration
Reduces the number of components and costs
required for protection
I
ncreases panel design flexibility
Quick visual determines module replacement status
to avoid loss of protection
Fast and simple to replace, minimizing maintenance
and downtime. No tools required
