SDSA1175 and SDSA 3-Phase Surge Protective Devices
SDSA1175
SDSA 3-Phase
Surgelogic
TM
SDSA1175 surge protective devices are designed and listed for indoor or
outdoor installation and surge suppression for single-phase three-wire 120/240 Vac or
two-wire 120 Vac 60 Hz electrical services. This product is ideal for panel builders as well
as manufacturers and integrators of instrumentation cabinets for industrial and
commercial applications for single-phase power systems. Two SDSA1175 surge
protection devices can be installed to provide suppression for 208Y/120 Vac three-phase
four-wire services.
Surgelogic
TM
SDSA 3-Phase surge protective devices are designed and listed for indoor
or outdoor installation and surge suppression for three-phase electrical services up to
600 Vac. The SDSA 3-Phase series is used extensively in service entrance panels to
provide an efficient and economical means of surge suppression and also ideal for point
of use applications for that added level of protection.
