£8.58
The Wöhner 05802 is a robust stand-off insulator with a female thread and threaded bolt, engineered to provide reliable electrical insulation and mechanical support for low voltage switchgear, busbar systems and industrial control panels. Featuring an M8 threaded bolt with M8 female thread and an overall 35 mm height, it provides a secure and versatile mounting solution whilst maintaining safe electrical clearances in demanding industrial environments.
Manufactured by Wöhner, the 05802 is produced from a durable, halogen-free insulating material and complies with IEC 61439-1:2020. Its excellent dielectric properties and robust construction make it an ideal choice for panel builders, OEMs and electrical engineers requiring dependable insulation components.
With a rated insulation voltage of 1500 V AC/DC, M8 threaded bolt with M8 female thread and a 32 mm width across flats, the Wöhner 05802 provides secure support for busbars, terminals and electrical assemblies in industrial power distribution equipment.
Stand-off insulators provide safe separation between live conductors and grounded metalwork whilst supporting busbars and electrical assemblies. They help maintain electrical clearances, improve operational safety and maximise the long-term reliability of industrial power distribution equipment.
The Wöhner 05802 is specifically designed for installations requiring a threaded bolt on one side and a female thread on the other. It should always be installed on flat mounting surfaces with the fixing points fully supported, as uneven mounting surfaces may introduce mechanical stress that can damage the insulator.
