Disconnectors STOR
 The STOR disconnectors are devices used as components of stationary distribution substations. They are able to switch electrical circuits ON & OFF in the no-load conditions. The devices are driven by a motor - in emergency by a manually turned crank handle. As opposed to the standard types of disconnectors, the moving set of contacts keeps in the same plane where the outlets are, and, therefore, even if opened, the disconnector occupies the same space. Thanks to this fact the installation space can be minimized. The device is fitted with auxiliary contacts extending status signals. Its modular design makes possible a range of optional configurations. |
