TD TD TD
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 solar string box and inverter
applications are available in 1100 and 1500 VDC in the 3+0
configuration.
Features & Benefits
FEATURES BENEFITS
Capability to clamp and
withstand high-energy
transients
No additional
overcurrent protection
devices required in
UL applications
Compact footprint
Visual life indicator
Ensures low-residual voltage during high-energy
surge events and higher nominal discharge current
to prevent disruption, downtime, and degradation or
damage to equipment
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
