DC protection

DC-side protection: WattKit LA6.25-1000 three-pole surge arresters for 1000V in type 2, Phoenix Contact VAL-SPP type 1+2 arresters up to 1000V DC with remote signalling, and Hager ESC227 and ESC425 modular contactors rated 25A with a 230V coil for circuit switching.

In direct current an arc does not self-extinguish, so these devices are built differently: a DC arrester has dedicated arc chambers and is not interchangeable with an AC one of the same rated voltage. Type 1+2 is what you need when the building has a lightning protection system.

Keep the distance between arrester and protected equipment under 10 metres.
