Together with the appropriate test adapters, WTL 4/2 STB Disconnect Test terminal blocks permit tapping into circuits by opening the busbar in the terminal with a single make-before-break action.
The design assures continuous operation of the circuit during the test procedure. The order in which disconnect and contact is made is determined by the length of the colorcoded plastic lug on the test adapters. The devices have a touch-safe design, and the combi-foot works with TS-32 and TS-34 DIN-rail mounting. Test cable and test adapter connect with a screwdriver. The blocks are UL-rated at 300V, 8A, and 26-10 awg.
