EOL3-277-20KA

Patent-pending 3-Pole In-Line Fused Surge Protector

for LED Drivers & Electronic Ballasts.

Indicator LED turns on at end-of-life.

EOL3-277-20KA is designed for use in conjunction

with LED Drivers to provide an additional

level of protection against powerline

disturbances in industrial and

commercial applications. Also

protects electronic fluorescent

and HID ballasts.

Features

• This 4-leaded device protects Line-Ground, Line-Neutral, and Neutral-Ground

in accordance with IEEE / ANSI C62.41.2 guidelines

• Provides additional protection at End-of-Life by

opening voltage to the fixture and turning off the fixture

• LED indicator will light when the EOL3 has reached End-of-Life.

This provides positive indication that the EOL3 needs to be replaced.

• Indicator flashes at “power-up” to provide confirmation that LED is functional.

• Two models:

- EOL3-277-20KA-L includes a local LED indicator (blue)

- EOL3-277-20KA-R is designed to operate a remotely-mounted

LED indicator (Purchased separately.)

• Protects against surges according to IEEE C62.41.2 C High (20kA and 10kV)

• Protects against surges according to ANSI C136.2

• Max surge current = 20,000 Amps using industry standard 8/20 µSec wave

• 7.0 Amp maximum load

• Surge Location Rated Category C3

• UL Recognized Component in the United States and Canada (UL1449)

• Complies with IEC 61643-11; 8.3.4.3

• High temp, flameproof plastic enclosure; 85ºC max surface temp rating

• Remote-mount LED indicator assembly requires a 0.25” mounting hole

• Patent Pending

•

EOL3-277-20KA is for use with any 100-277V power supply, LED Driver,

e-HID Ballast, Electronic Fluorescent Ballast, Induction Generator
