Manual drive for a connector with earthing, under-line mounting, rotary movement of NRA E-13.5 w.II 03-511

Manual drives for disconnectors – reliability and precision in operation

This manual drive, designed for disconnectors with earthing, is a key element enabling safe and effective control of electrical circuits. Mounted under the line, it provides smooth rotational movement, essential for the proper operation of NRA-u E-13.5 w.II disconnector. It is an ideal solution for both professional installers and end-users looking for a reliable way to manually switch circuits.

This drive is compatible with disconnectors manufactured by ALPAR, and its design is intended for easy installation and operation. Mounting with two M10 screws guarantees stability and a secure connection with the disconnector drive mechanism. Using a manual drive allows for precise control, especially in situations requiring manual intervention or lack of power access.

Design and application

The NRA-u E-13.5 w.II manual drive is an integral part of overhead disconnectors of the ON (OUN) type and their variants (ONp, OUNp, ONM, OUNM). Its task is to provide the possibility of manual opening and closing of the electrical circuit. The drive design is based on a solid frame and a bearing movable beam, which translates into smoothness and precision of operation. The use of high-quality materials and a zinc coating protecting against corrosion guarantees long-lasting and trouble-free operation even in difficult atmospheric conditions.
