Can the fuses in the IMA or IBA MA modules be replaced?

Issue:
Can the fuses in the IMA or IBA MA modules be replaced?

Product Line:
Surge Protective Devices (SPDs)

Environment:
Maintenance

Cause:
Replacement

Resolution:
There are no replaceable fuses in the IMA or IBA MA modules. These modules use thermally protected MOVs. If either LED on an MA module is not lit, the module should be replaced. If both green LEDs are not lit and the diagnostic display panel has power, it indicates a loss of power to that phase or the module needs replacement. If the correct voltage is present on that phase, the MA module will need to be replaced.
