Surge protective device for linear direct current systems

Surge protection for direct current

Due to their structure, direct current systems exhibit a different behavior during regular operation and in the event of an error than alternating current systems. Consequently, they require specific surge protective devices. Depending on the installation location and requirements, these SPDs are subdivided into type 1 and type 2 protective devices.
