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
It MIGHT mean that the connectors can be re-used, but only for a limited number of times, which seems reasonable as they are intended to be part of the PERMANENT installation. Limited re-use is reasonable, for example to replace a decorative luminaire that is connected to the fixed wiring by Wagos.
Or it MIGHT mean that they can only withstand a limited number of through faults, full short circuit current until the OCPD operates. That in my view is a rather suspect restriction. IMHO, Wago or other connectors should be able to withstand anything that the connected cables can withstand. A low quality or misused installation might be subjected to thousands of MCB trips over its lifetime.
Or it might mean that the connectors can only withstand a limited number of disconnections whilst live and under load. That is a reasonable restriction, remembering that any such (mis)use almost certainly constitutes "Live working" and should be avoided except under certain very limited circumstances.
