An innovator in the mining industry for over 70 years

With our roots founded in mining over 7 decades ago, Bender has become a global leader in electrical safety technology and ground fault protection for mining applications.

In this harsh working environment, people and processes depend on safe operations and reliable functioning of mining plant and equipment.

Bender monitoring devices aid safer working conditions and maximum availability of the technical equipment and systems required to extract mineral resources. 

Our years of research, design and technical experience has led to the development of a broad portfolio of products which monitor, detect and provide early warning of developing causes of electrical failure. Our solutions help safeguard personnel, equipment, and processes, preventing failure and reducing repair and maintenance costs.

As an innovator in the field of electrical safety, Bender technology meets stringent quality testing and is designed to comply with relevant industry standards.
