NOTES:
1. Dimensions are in inches.
2. Metric equivalents are given for general information only.
3. Unless otherwise specified, tolerance is ±.031 (0.79 mm).
4. The shape of the circuit breaker is shown for information only. Slight deviations from this outline drawing,
which do not alter the functional aspect of the device, are acceptable.
5. Hex mounting nut .375-32 UNEF-2B thread, .093 ±.005 (2.36 mm ±0.13 mm) thick or equivalent MS25082-
20, -B20.
6. 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.
