In order to protect sensitive devices, you need to implement type 3 device protection as the third and last protection stage. Important requirement: type 2 surge protection must already be installed in the sub-distribution.
The internal disconnect device and the integrated arrester backup fuses provide increased safety in the event of electrical and thermal overload, regardless of the installed backup fuse.
For this reason, the PLUGTRAB-SEC is the reliable surge protection solution for AC and DC end devices.
PLUGTRAB SEC also has the advantage that the modules are pluggable. The base element and plug are coded accordingly. Mismatching of plugs from different voltage levels is therefore prevented.
The pluggable design offers the following advantages:
The operating state of all modes of protection of PLUGTRAB SEC is monitored.
In the event of an error, the plugs are thermally disconnected. Clear signaling takes place directly on the module. A floating PDT contact is also monitored at the same time. Easy-maintenance remote signaling can therefore be implemented.
The large marking area on the protective devices also ensures accurate identification on site.
