ASCO Model 160 (EDCO CX and RM-CX Series)
Surge Protectective Device (SPD)
Introduction
The
ASCO Model 160
Surge Protective Devices (SPDs) implement three-
stage hybrid technology. The SPDs address over-voltage transients with a
primary Gas Discharge Tube (GDT) and secondary Silicon Avalanche Diode
(SAD) components. Overcurrent protection is mitigated with solid-state
resettable fuses — PTCs.
The Model 160 SPDs are designed in accordance with NFPA 780
requirements, with up to 20 kA of surge current capability. The Model 160
with Gas 14th character has an isolated ground option and is recommended
for use at the camera-end.
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
• Apply appropriate personal protective equipment (PPE) and follow safe
electrical work practices. See NFPA 70E, NOM-029-STPS or CSA Z462.
•
This equipment must only be installed and serviced by qualified electri
-
cal personnel.
•
