Citel DS240S-280DC SPD, DC or type 2, PV network 280Vdc
DS240S-DC surge protectors are designed to protect equipment connected to DC (and AC) power supplies from lightning surges. It is based on varistors matched to the network voltage: the varistors have thermal disconnection devices to control any end-of-life. These SPD are DIN rail compatible and is connected in parallel on the line to be protected.
Features
- DC or PV power surge protector 280V DC
- Compact design Imax: 40 kA Pluggable module Remote signaling (option)
- Very low Up protection level
