The LV848558 is a grounding kit KMT from the MasterPact range, designed as an insulation accessory for earthing connections on MasterPact fixed-mount circuit breakers.
Fixed mounting mode means this kit bolts directly to the breaker chassis — no DIN-rail adapter, no sliding mechanism. It's a one-time install during panel build, sized for the MTZ2/MTZ3 frame footprint.
The LV848558 carries an active lifecycle status, meaning Schneider continues to manufacture it as a current-production accessory for the MasterPact MTZ2/MTZ3 platform.
The LV848558 provides the earthing connection path for the MasterPact MTZ2/MTZ3 fixed-mount breaker. It is the safety ground bond that ensures the breaker chassis is at earth potential.
