13NOVA™ STS Single-Tank,Triple-Single,Electronically ControlledRecloserINSTALLATION AND OPERATION INSTRUCTIONS MN280046EN May 2016AccessoriesAuxiliary switchA single-stage auxiliary switch can be provided as anaccessory on each phase of the recloser. Each switchconsists of two independent contacts that permit anydesired combination of “a” and “b” contacts, allowing forremote monitoring of the recloser.The switch contacts are insulated for 600 V and have acontinuous current rating of 10 A. Their interrupting ratingsare shown in Table 11.Table 11 Auxiliary Switch Interrupting RatingsVoltsInductiveAC (A)Non-InductiveAC (A)InductiveDC (A)Non-InductiveDC (A)24 – – 15.0 20.048 – – 7.5 10.0120 60 80 – –125 – – 1.5 2.0240 30 60 – –250 – – 0.45 0.5Table 12 Auxiliary Switch Pin Contacts and Cable WireColorsRecloser Phase* Contact Type** Wire Color*** Receptacle PinA-phase a blackwhiteABA-phase b redgreenCCB-phase a orangeblueEFB-phase b white/blackred/blackGHC-phase a green/blackorange/blackJKC-phase b blue/blackblack/whiteLMunused unused unused N, P* See Figure 6.

Eaton recommends terminal connectionto copper wires to optimize the electrical connection.Aluminum cables may produce aluminum oxide sufficient tocompromise the electrical connections.Anti-oxide coatings for temporary protection of wire-brushed, aluminum cable connections to flat-pad or studterminals must be maintained at intervals determined bythe customer based on load current, climate, and otherinstallation conditions.Eyebolt terminals are recommended for copper conductorsonly.
