OCTOBER 17, 2008 - WAGO added the 873-903 three-pole model to the 873 Series LUMI-NUTS luminaire disconnect line. The 873-903 is a safe electrical disconnect for high-feature linear fluorescent fixtures that use a dimming circuit or the Digital Addressable Lighting Interface (DALI) protocol. LUMI-NUTS meets NEC410.74 (G), CEC30-308 (4) and CSA/UL Standard 2459 for Insulated Multi-Pole Splicing Wire Connectors, ensuring safe service of linear fluorescent fixtures. Power input/line side accommodates AWG #18-12 solid and AWG #16-12 stranded conductors; ballast/load side accepts industry standard AWG #18 solid conductors.
The 873-903 provides a best-in-class rating of 6A/600V and utilizes a UL94V-0 flame-rated polyamide 6.6 housing for flame retardation. A touch-proof design — whether mated or unmated — eliminates need to disconnect power for service. An integrated locking latch prevents unintentional separation of the mating halves. The connectors are keyed for mis-mating protection and color-coded for simplified wiring.
Mating halves carry on-unit markings to further reduce wiring errors. LUMI-NUTS connectors provide PUSH WIRE terminations — insert prepared conductor into unit. Terminations are maintenance-free, as well as vibration- and temperature-cycling resistant. “LUMI-NUTS has undergone extreme testing in excess of 39A for 500 hours without failure,” said Jim Bachle WAGO Industry Manager-Lighting Market.
“This performance confirms LUMI-NUTS suitability for applications ranging from retrofits to elevators.” WAGO is the leader in CAGE CLAMP Spring Pressure Connection Technology that eliminates loose wires resulting from vibration and temperature cycling, while providing highly reliable, corrosion-resistant and maintenance-free connections. Products: DIN-rail, PCB and chassis mount terminal blocks; signal conditioners; WAGO-I/O-SYSTEM and more.
