What is the field-installable Kirk Key lnterlock mounting provision for the Powerpact M, P and R frame breakers?
Applies to PowerPact M, P and R
For Powerpact M, P and R breakers, the Kirk Key Interlock provision is NOT available for field installation. The provision is only available factory installed on the breaker cover. For an existing breaker, instead of having to replace the breaker, customer can return the breaker/cover via return tags to the plant to have the lock ``provision`` (mounting bracket) installed, based on the below. Then you can buy a Kirk lock from the vendor direct to install on the breaker.
NOTE: Return options are below based on type of breaker you have.
PowerPact M: Unit Mount = Return of Cover Only is acceptable I Line = Return of Cover Only is acceptable
PowerPact P: Unit Mount = Return Complete Breaker with cover I Line = Return of Cover Only is acceptable
PowerPact R: Unit Mount = Return of Cover Only is acceptable I Line = Return of Cover Only is acceptable
If the existing breaker has a padlock attachment, it will have to be removed. The key lock and padlock take up the same position on the breaker cover.
When returning the Breaker/Cover ask for ``suffix JA (for M or P frame) or JK (for M, P or R frame)`` for kirk provision. The return TAGs will be for a ``code 50 return and repair``.
Suffix for ``JR`` for Schneider (Federal Pioneer) provision is no longer available, since about Sept. 2013.
