Lightning/surge protective device, according to type 1/2 / class I/II, for linear, unipolar DC supply systems up to 1000 V DC, for DIN rail mounting, with remote indication contact.
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.
