Phoenix Contact DC Line Surge Protection

DC surge protectors are devices that are designed specifically for direct current lines. Unlike AC, that oscillates back and forth, DC remains at a constant voltage. This makes arcing a bigger hazard and the surge protection device must be designed with additional arc extinguishing measures.

Phoenix Contact Type 1+2 Combined Lightning Current and Surge Arresters fulfills the high requirements in terms of discharge capacity as a type 1 current arrestor, as well as providing type 2 surge protection. 

Phoenix Contact Type 1+2 SPECIAL Combined Lightning Current and Surge Arresters differ from type 1+2 in that the SPECIAL Combined Lightning and Surge Arresters contain two independent protective devices that are connected in parallel. The voltage-switching spark gap (SPD type 1+2) works ideally in combination with a voltage-limiting varistor (SPD type 2). When combined, the two autonomous protective devices in one block ensure optimum response, optimal system protection and a long service life.

Phoenix Contact Type 2 SPDs are typically installed in machine and sub-distribution control cabinets. They perform the second protection level in a three-stage surge protection solution. Type 2 SPDs must be able to safely discharge overvoltages from switching operations or indirect lightning strikes. Overvoltages caused by switching operations are often highly dynamic and occur much more frequently than overvoltages cause by indirect lightning strikes. 

Phoenix Contact Type 3 SPDs are typically installed immediately upstream of the end devices that need protecting, therefore, they are also referred to as “device protection.”
