Superior Performance
Square D brand Surgelogic SDSA 3-Phase
SPDs utilize high-energy suppression
circuitry that can be located at any point
in the electrical system. They have the
flexibility to be used with or without an
Overcurrent Protective Device (OCPD).
SDSA 3-Phase SPDs provide surge
suppression for equipment from severe
transient activity. Each metal oxide varistor
(MOV) is individually fused and the products
carry a NEMA Type 4X rating suitable for
installing indoors, outdoors, or in other harsh
environments.
