Description
The Cooper Bussmann®multi-pole, modular Surge Protective Device
(SPD) (with three-step DC switching device) features
easy
ID™ visual
indication and optional remote contact signaling (floating changeover
contact) for use in PV systems.
These complete surge protective devices are suitable for all
PV systems in accordance with UL 1449 3rd Edition and
IEC 60364-7-712. Includes a five year limited warranty.
These prewired solutions consist of a base and locking modules that
feature a combined disconnection and short-circuiting (shunting)
device with safe electrical isolation to prevent fire damage due to DC
arcs. An integrated DC fuse allows safe module replacement without
arc formation.
In case of insulation faults in the generator circuit, a reliable and
tested fault-resistant Y circuit prevents damage to the surge
protective devices.

Visual Status Indication
Short-Circuit Interrupting (SCI) Technology
The green and red visual indicator flags show the module
protective status (green = good, red = replace). Apart from this
visual indication, the remote signaling option features a three
terminal floating changeover contact that can be used as a
make or break contact depending on the particular monitoring
system design employed.
