TO-3 Insulating Covers
Insulating covers are designed to provide protection from accidental shock
during field service or repair.
Pan head screws not provided–MS 51957-30 or equivalent recommended–secure the cover
to the TO-3. At the typical mounting screw torque of 0.68–0.90 Nm (6-8 inch pounds), the
TO-3 cover material cold-flows around the screw head to securely fasten the cover.
Included are No.6 split washers as inserts to provide electrical connection of mounting screws
to the TO-3 collector and an insulating snap-in cover for the screw heads. A test probe hole is
provided in the top of the cover.
The 8903VB is made from thermoplastic polyester that meets the requirements of UL Bulletin
94 V-O. In addition to its excellent flammability rating, thermoplastic polyester offers resistance
to most chemical environments, heat deflection temperature to 215.6°C (420°F) and UL contin-
uous use temperature of 130°C (266°F).
