Highlights & Technology

Deploy maintenance with intelligence and only as it’s needed, limiting truck rolls, speeding reaction time, and lowering overall maintenance costs - all while reducing on-site exposure. 

Targeted maintenance enables utility technicians to repair a small issue before it causes a substantial failure that may require equipment replacement or an entire overhaul of a high-cost asset.

Along with its array of sensors, the Optimizer3 monitors both the mechanical and electrical performance of the circuit breaker to perform trending analysis that predicts the date of future service.

Performance measurements including opening (trip) and closing times, arc duration, clearing time, and open/close travel times and velocities are automatically analyzed to provide a full assessment of the circuit breaker’s health.
