Are the fuses replaceable in the IMA or IBA MA modules?

Issue:
Are the fuses replaceable in the IMA or IBA MA modules?

Product Line:
Surge Protective Devices (SPDs)

Environment:
Maintenance

Cause:
Replacement

Resolution:
There are no replaceable fuses in the IMA or IBA MA modules.
The modules are configured with thermally protected MOVs. On an MA module, if either LED is not lit, the module should be replaced. If both green LEDs are not lit and the diagnostic display panel has power, then power has been lost to that phase or the module should be replaced. If the correct voltage is present on that phase then the MA module will need to be replaced.
