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. 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 MS35265-26 or equivalent.
