1. Recommended quantities are as follows:

Domestic - One (1) complete set for each ten (10) breakers or fraction thereofinstalled for each rating.

International - One (1) complete set for each five (5) breaker or fraction thereofinstalled for each rating.

NOTE: Figure Reference parts marked with delta (∆ ) are minimum that shouldbe ordered for normal duty applications. For heavy-duty applications,all applicable Figure Reference parts should be ordered.

2. The parts listed cover an indefinite period of time. With normal duty andmaintenance, replacement will be infrequent.

3. Standard hardware (screws, nuts, lockwasher, etc.) is not included with the parts.

4. Where continuity of service is mandatory, a spare breaker is recommended

When ordering, always state type of circuit breaker and serial number from breakernameplate in addition to part description and ordering number. State the quantity,description, and ordering number of each assembly or part required, as applicable.

EXAMPLE: To order moving contact assemblies for a typical K-600 circuit breaker,provide the following:

For a type K-600 circuit breakerSerial No.39402-22-2-4A (From breaker nameplate)S.O. 33-39402Quantity-2 (Fig. Reg. 4B, page 8) Moving Contact Assemblies 706783T02

The recommended spares in this bulletin apply only to circuit breakers having thefeatures listed. For example, if your circuit breaker is stationary mounted, you woulddisregard the primary and secondary disconnect assemblies (Fig. Ref., 27A,B,C,D,E,and 28). If your circuit breaker has some special feature not listed, provide completedescription of feature, such as - Shunt Trip - 120 Volts AC, in addition to otherinformation requested in example above.

When ordering current-limiting fuses, always specify the continuous current rating inaddition to the ordering number.

NOTE: Fig. Ref. parts marked with a bullet (•). On circuit breakers equipped with solidstate overcurrent trip devices, as designated by the “S” at the end of the circuitbreaker “Type”, it is necessary to replace both the solid state logic assemblyand the lower molding assembly when changing the circuit breaker to a newAMPERE TAP range.
