Which DC voltage version do I need for my solar array?

Pick the version whose continuous operating voltage (Uc) sits above your system's max DC voltage. Options run from 100V up to 1000V nominal, covering most solar PV, battery, and EV charging setups. Choosing too low a rating risks nuisance failures.

How does this surge protector mount and wire up?

It clips onto a standard 35mm DIN rail inside your enclosure. Wiring connects through screw terminals that accept 1.5 to 35 mm cable. It protects L+ and L- to PE, so wire your earth connection properly.

What surge current can it actually dissipate?

Nominal discharge current (In) ranges from 20kA to 60kA depending on the model. Max discharge handles even higher transient spikes. Match the rating to your site's lightning exposure and protection level.
