WAGO 2273 "Limited number of current-interrupting operations"
Former Community Member
The enclosed instructions declare:
"Limited number of current-interrupting operations" is written in the leaflet enclosed with the assortment box for these in 2, 3, 4, 5 and 8 way for 0.5 to 2.5 mm2 solid conductor 24 A
Google suggest the phase comes from a UL standard...
Limited current interruption — Mating-type multi-pole splicing wire connectors are marked " Limited Number of Current Interrupting Operations, " or the equivalent, to identify that the device has been investigated for a maximum of 10 make-and-break current operations.
so I suspect it's a case of the closest US standard they could find was one for pluggable connectors (or one that also covered pluggable connectors), and that standard demands that the phase be included in the documentation.
