IG Series
Specification
The Surge Protective Device shall be listed by CSA to ANSI/UL 1449 3rd Edition for Type 1 and Type 2 locations. The
Surge Protective Device shall provide protection between each phase conductor and ground. The Maximum
Continuous Operating Voltage (MCOV) shall be a minimum of ____volts AC between phase and ground. When subjected
to the ANSI / UL 1449 3rd Edition 20kA test impulses, the Voltage Protection Rating shall be no greater than 700 volts
Line to Neutral, 1200 volts Line to Line. The Surge Protective Device shall employ Large MOV technology and provide
individual component thermal protection and monitoring, utilizing a green LED status indicator. The failure of a
single component turns the LED OFF. The IG1240RC3 rainproof housing shall be constructed of UV resistant
polycarbonate, or material of equal strength and UV resistance, and tested to UL Type 3R standards for outdoor use. A
one half inch polycarbonate threaded nipple and metal locknut shall be provided. Leads shall be 12 gauge minimum and
24 inches in length. The IG3240RC3 rainproof housing shall be formed of 18 gauge powder coated sheet metal tested
to UL Type 3R standards for outdoor use. (A one half inch threaded nipple and metal locknut shall be provided). Leads
shall be 12 gauge minimum and 24 inches in length. The Surge Protective Device shall carry a 5-year product warranty
(IG3240RC3 10-year warranty) and also carry a $__________ connected equipment coverage warranty for ve years on
appliances and electronics.
