What voltages can SDSA1175 be used on? Is it rated for a 120v single phase application?
single phase application
The SDSA1175 is applicable to 120/240Vac 1PH/3W systems. Use on a 120Vac 1PH/2W system is not recommended since the Indicating LED will not be functional on this system. The correct unit to use is the SDSA1175T for the 120v 2 wire circuit.
Two SDSA1175 may be applied to a 208Y/120Vac 3PH/4W system. Systems must be solidly grounded. Do not use the SDSA1175 on ungrounded systems.
