Superior Performance
Square D brand Surgelogic SDSA3650 SPDs
utilize high-energy suppression circuitry that
can be located at any point in the electrical
system. As a Type 1 rated device, they have
the flexibility to be used with or without an
Overcurrent Protection Device (OCPD).
SDSA3650 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.
Easy Installation
Surgelogic SDSA3650 SPDs are some of
the most versatile, yet compact devices
available on the market today. This compact
package can be mounted on an electrical
panel, meter socket, or inside electrical
control cabinets.
