About Us

I-Gard is a wholly owned subsidiary of Telema Spa, the world's largest supplier of power resistors with companies operating across the globe.

From our beginnings as a power resistor supplier to the Canadian market in 1982, we have grown into the established industry expert in resistance grounding and ground fault protection.

The catalyst for this change was the acquisition of the Federal Pioneer line of ground fault protection products in 2001.


Our dedicated and experienced R&D staff, with input from sales and marketing, continually look to improve the functionality of our products to meet increasing expectations for electrical safety.

We take pride in our collaboration with leading US and Canadian universities in developing and exploring the latest technological advances in electrical safety. We're a proud sponsor of the Electro-Federation Canada Scholarship Foundation (Electro-Federation Canada Scholarship Foundation). 

From patented products such as Gemini and Fusion to unique functionality of the DSP relay and Sentri HRG system- we continue to innovate with your reliability and electrical safety as our main goal.
