Success Story

"Smaller Yet More Powerful"


Our latest challenge required delivering more performance from a smaller and safer latching relay for the multi-year, multi-million smart meter rollouts in two major European markets.

To meet the stricter short circuit and dielectric requirements of the French and UK markets, our team designed the smaller, yet more powerful K125—a fully-certified UC3 100A latching relay.

Rated at 277VAC, the K125 remains functional even after a 6000A short circuit and exceeds all safety standards. The K125 is just one example of how KG Technologies achieves cost-to-performance balance within its design methodology.

We were able to reduce the size of our latching relays while also improving relay performance at a advantageous price point – all with fully compliant UC3 relays.

This achievement has positioned us well to support both the French and UK metering market demands over the next 10 years.
