The LV848559 is a grounding kit from the MasterPact range, designed specifically for MasterPact MTZ2 and MTZ3 drawout circuit breakers. It provides the earthing connections for the drawout cradle, ensuring the breaker frame is grounded when racked into the connected position. Classified as an insulation accessory, this KTM kit mounts in the drawout cassette and establishes a low-impedance path to ground through the cradle's earthing contacts. It is a factory-specified component for any MTZ2 or MTZ3 drawout installation — not optional for the ground-fault protection scheme.
Integration note
Drawout mounting means the kit installs into the fixed cradle, not the moving breaker carriage. The grounding contacts engage automatically as the breaker is racked from test/disconnected to connected position. Verify the cradle's earthing bar is present and torqued to the panel ground bus before inserting the breaker.
