GemStart 5 - Beyond a simple motor protection

Modern industries massively use electrical motor in most of manufacturing processes. Indeed, 70% of expenses in industries involve motors. In accordance with the new directives aiming at reducing the energy bill, electrical motors of high output energy allow energy saving and efficiency.

This saving is possible only if your motor protections are optimal. Choosing a protection for your motors is therefore essential to make your electrical installations and investments sustainable.

Le Gemstart5® is a motor protection relay perfectly dedicated to protect, control and monitor electrical motors and their applications. Discover more about its functionalities.
