The coordinated approach per the IEEE 8.6.3 recommends two stages of protection – one at the main service and one at the distribution or sub panel.
SERVICE ENTRANCE: FEEDING ENTIRE FACILITY
This is the first stage of protection from lightning and other external surges. This stage requires a high peak surge current (large kA/Phase rating) to protect the entire facility.
PTX400 (400 Ka/Phase) 20 Yr. Warranty
PTX300 (300 kA/Phase) 20 Yr. Warranty
SUB PANELS FEEDING: MOTOR CONTROL CENTERS, PROCESS CONTROL EQUIPMENT, LARGE FIELD EQUIPMENT, SECURITY SYSTEMS, DATA CENTERS, MEDICAL EQUIPMENT, COMPUTER LABS, OFFICES
This is the second stage of lightning and surge protection covering panels from external and cross circuit transients. This stage will remove the remnant of let-through voltage from the main service and address all of the internally generated transients.
PTX160 (160 kA/Phase) 20 Yr. Warranty –Use for panels feeding: compressors, mixers, motors, outside lights, drives power line carriers, leak detectors/environmental monitoring equipment, and panels downstream from Ferroresonant transformers.
PTE160 (160kA/Phase) 20 Yr Warranty (‘E’ refers to enhanced, providing sine wave tracking and filtering using capacitance) –Protects panels feeding: batch computers, point of sale registers, scales, office computers, labs, data centers and other very sensitive electronics.
MOTOR CONTROL CENTERS ● Use PTX400 at Main and PTX160-NN400L internally fused unit that installs on the incoming lugs (Usually the top left bucket) of the MCC protecting all the motors
HS-P-SP (80kA/Phase) 10 Yr. Warranty – Includes RJ11/14 Protection and Dry Contacts –Sine wave tracking for AC applications, use to protect load side (drive electronics, PLC’s, etc.) of any step-down transformer.
HT or HS (Sine Wave Tracking) 25kA-80kA/Phase, 10 Yr. Warranty –Parallel or series wired for lower voltage AC & DC applications – 24VDC to 250VAC
PROCESS CONTROL EQUIPMENT ● Use PTX 160 OR PTX080 at sub panel
D(x)S-(y)-2ML (x)= 2,4,6 conductors / (y)= 15,33,53,140 operating voltages –Protects data lines or 4-20 ml control current loops – can be placed at the processors and at the transmitters.
HS-P-SP (80kA/Phase) 10 Yr. Warranty – Includes RJ11/14 Protection and Dry Contacts –Sine wave tracking for AC applications, use to protect scales and other individual electronic loads.
TELECOMMUNICATIONS/SECURITY SYSTEMS ● Use PTX160 at sub panel
ITC-(x)T-ISDN (x)= no. of terminals –Protects phone, ISDN, fax, data lines
MDF-(x)-ISDN (x)= 6 or 25 pair –On main distribution frame to protect incoming phone service
COAX-(BNC orF)-1.5GHz (1 in/1 out) –Protects both remote site camera and monitoring station
D(x)S-(y)-2ML (x)= 2,4,6 conductors / (y)= 15,33,53,140 operating voltages –Protects T-1 lines and other dedicated data lines to remote site cameras, access card readers (up to 2.0 MDPS)
HS-P-SP (80kA/Phase) 10 Yr. Warranty – Includes RJ11/14 Protection and Dry Contacts — Sine Wave Tracking for AC Applications: Protects Both AC Circuit and Comm Line to Card Reader, Us for Systems that require both AC and RJ protection
