Disconnect Relays

Disconnect Relays

The Johnson Electric product line for smart meters aligns with the requirements of the electric power industry’s smart grid initiative. The Ledex-EM and Ledex-BLP products are bi-stable latching relays custom designed to provide the highest electrical performance in a compact package.

The compact relays utilize innovative technology for accurate switching with low contact resistance and lowest bounce time. The disconnect relays provide the highest magnet tamper resistance to prevent switching by an external magnetic field as well as safe electrical operation.
