Is it possible to use an SDSA1175 on a 480V or 240V, single-phase system?
The SDSA1175 is meant for use in a 120/240V single-phase 3-wire/2-wire setup. Using this device on a higher voltage system will cause damage to the SPD. For a 480V system, the suitable SDSA series SPD to use is the SDSA4040 (for 480Y/277) or SDSA4040D (for 480V Delta). For a 240V system, the appropriate SDSA series SPD to use is the SDSA2040 (for a 208Y/120) or SDSA2040D (for a 240 Delta).
