The LV848826 is a sensor plug for the Schneider Electric MasterPact MTZ3 air circuit breaker equipped with a MicroLogic X control unit, rated at 3000 A. It is the accessory that connects the breaker's current transformers to the electronic trip unit, feeding the measurement and protection algorithms.
What the 3000 A Rating Means
The 3000 A rating is the line-rated current of the MasterPact MTZ3 frame this sensor plug mates with. It defines the maximum continuous current the breaker assembly can carry without exceeding thermal limits. For a buyer, this number is the hard fit constraint: the sensor plug must match the frame rating exactly — a 3000 A plug will not work in a 2000 A or 4000 A frame, and vice versa.
Deployment Context
It is a control-unit accessory that is swapped when upgrading or replacing the MicroLogic X trip unit. The MTZ3 itself is a draw-out air circuit breaker used as a main or feeder breaker in low-voltage switchgear (IEC 61439-1) for high-current industrial and commercial power distribution.
