The Challenge
Underground mining demands some of the toughest products in the world. Safe and reliable switching of AC circuits is essential in these environments, where downtime can cost millions and safety is always on the line.
Traditional contactor solutions are often heavy, maintenance-intensive, or no longer supported by OEMs, leaving operators searching for replacements that meet strict safety and performance requirements.

The Leveltec Approach
Understand
Leveltec selected Hansen Electric for the Australian and New Zealand market because the HR-VS range was originally engineered for Hansen’s own mining equipment and has been proven globally for more than 10 years. With over 30,000 contactors installed worldwide, Hansen provides a tested solution that fills the gap left by discontinued legacy products.
Solve
New installations are straightforward, but retrofits are rarely simple. Leveltec works with customers to design bespoke mounting and integration solutions, making retrofits possible in the workshop or the field, without compromising safety or compliance.
Support
With direct access to Hansen’s engineering team, product optimisation is always on the table to meet new challenges. Locally, Leveltec provides stocked products, technical support, and national coverage, ensuring operators can deploy, maintain, and trust Hansen contactors on site.
