Superior Performance
Square D brand Surgelogic QO loadcenter
SPDs utilize high-energy circuitry that
provides surge suppression from severe
transient activity. Each MOV is individually
fused.
Directly connected to the equipment bus,
the QO2175SB delivers superior surge
suppression performance by providing the
shortest lead lengths.
Easy Installation
Quick plug-on device for use in a QO
loadcenter or NQ panelboard. The SPD
requires two adjacent mounting spaces.
Warranty
The QO2175SB warranty is 3 years.
