Manual drive for isolator without earthing, overline mounting, rotary motion NRA E-10.5 w.I 03-500

Manual drive for connector – reliability and ease of operation

This manual drive, designed for connectors without an earthing conductor, is a key element ensuring safe and efficient switching of circuits in overhead lines. Mounted above the line, it offers rotational movement, making it easier to maneuver and control the flow of energy. It is an ideal solution for both professional installers and end-users who value solid workmanship and ease of use.

Design and application

The NRA E-10.5 w.I manual drive is designed to work with ALPAR ON (OUN) III SA 24/4 series overhead connectors. Its main task is to enable manual control of the connector, which is particularly important in emergency situations or during maintenance work. Mounting is done with two M10 screws, ensuring a stable and secure connection to the connector's drive mechanism. The drive's design has been carefully considered to ensure simultaneous closing and opening of all poles of the connector, increasing the safety and efficiency of operations.
