Earthing rod for disconnectors 400 A ST72

Earthing device for 400 A disconnectors – safety and reliability in the power grid

This earthing device, designed for 400A disconnectors, is a key element ensuring safe and efficient maintenance and repair work in power grids. It enables effective grounding of overhead lines by mounting in place of standard fuses, minimizing the risk of electric shock and damage. This is a solid solution for both professional installers and those responsible for maintaining power continuity.

Design and application

The ST72 earthing device is designed to work with 400A disconnectors equipped with 4 poles (3+N). Its design allows for quick and easy mounting in the fuse base, replacing standard inserts. Made of durable materials, it provides a reliable connection to earth, which is particularly important during work under voltage or near energized equipment. A 1/2 inch square key spindle allows for precise tightening with a torque of 8 to 50 Nm, guaranteeing connection stability.
