TO-3 Insulating Covers are designed to provide protection from accidental shock during field service or repair.
8903 Screw Mounted Cover
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 .68 - .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 continuous use temperature of 130 °C
(266 °F).
8909 Snap on Cover
Designed to prevent accidental electrical shock, the 8909 fits TO-3 case styles. A test probe hole in top
eliminates the need to remove cover for testing. Recommended for low vibration applications. A precise
friction fit is required for proper assembly. Please read the
on the fit problems that can arise.
engineering information release
The 8903 cover shown above is recommended for most applications due to the typical size variation of the
TO-3 package.
