1SCA022081R9340

ABB 1SCA022081R9340 (OETLZW15) is a mechanical interlock mechanism used with ABB OT series switch-disconnectors. It is designed for two 3- or 4-pole switches and has a 500 mm shaft distance. The interlock prevents one switch from being switched to ON when the other switch is not in the required position, helping provide safe changeover operation. It is suitable for larger OT switch-disconnector frames, including OT315…4000E / OT800U…2000U.
