Internal tooth lockwasher, .507/.493 O.D., .392/.382 I.D., .025 .005 (0.64 mm 0.13mm) thick, stainless steel or equivalent MS35333-134. 7. The effective bushing thread length (not including mounting hardware) is .280 (7.11 mm) minimum. 8. Marking may appear on any surface except the mounting surface. 9. Lock ring not required if on-off plate has locking tab. 10. Numerical marking optional on circuit diagram. 11. Sealscrew, .138-32 UNC-2A x .312 (7.92 mm) long, stainless steel number 18-8 (type 347) MS35265-25 or equivalent with appropriate O-rings. O-rings should be chosen to enable the circuit breaker to meet the performance requirements of this specification. Possible source: AMP Hexseal Corporation. 12. Use of panel screws will enhance circuit breaker shock and vibration characteristics. 13. Threaded inserts exceed height of bushing by .005 to .015 (0.13 mm to 0.38 mm). 14. For configuration 2 add "S" at end of dash number for screw terminals with insulating block (see table I). When circuit breakers are subjected to the resistance to solvents test, the insulating block shall be removed and shall not be tested. Main terminal screw MS35265-25 or equivalent. FIGURE 1.
