NOTES:
1. Body molding material: It is recommended that type MAI-60 or GDI-30F of American Society
For Testing and Materials ASTM-D5948 be considered for meeting the body molding material
requirements of this specification.
2. For submarine applications use FHN41WB or FHN41WBS.
3. EMI/RFI shielded type fuseholders are equivalent to the non-shielded type fuseholders with the
addition of EMI/RFI shielding cap and mounting nut assembly.
4. To assure maximum shielding effectiveness mounting nut must be torqued to 15-20 inch-pounds
over an electrically conductive panel surface, 1.26 inch minimum diameter.
