385V ac, 500V dc 40kA BSPM 1Pole Arrester, DIN Rail Mounting
**Cooper Bussmann SPD Solutions - IEC**
The Cooper Bussman IEC SPD solution consists of a base and locking module that features a combined diskonnection 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. 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.
