Issue:
Can the leads or wires be lengthened on the SDSA1175?
Product Line:
Surge Arrestors
Environment:
SDSA1175
Resolution:
No. To obtain the maximum system performance, locate the device as close to the circuit being addressed as possible to minimize the interconnecting wiring length. For every foot of wire length, approximately 160 Volts (6 kV / 3 kA, 8/20 microsecond) is added to the suppressed voltage. The Voltage Protection Rating (VPR) is located on the device nameplate and is measured six inches from the enclosure sidewall, according to UL® 1449 test standards. Square D does not recommend adding length to the leads. Additional length would change the clamping voltage from published specifications.
