Issue:
What is the PowerpacT equivalent to an KAL, KAP, or KAF style Mag-Gard MCP (motor circuit protector)?
Product Line:
Legacy KAL type circuit breakers
Resolution:
KA type Mag-Gard motor circuit protectors (MCPs) can be replaced by PowerpacT MCPs, but there are some important differences. These two families of breakers have different dimensions, connection points, and accessories. Because of this, the equipment they are installed in will usually require some modification and in some cases, replacement of the equipment will be necessary. Please see attached for the different dimensions.
NOTE: If the KAL is installed in an old KA individual enclosure, then the below H or J Frame PowerpacT WILL NOT WORK. It will require a brand new enclosure and a new thermal/magnetic breaker with 'instantaneous' adjustments and NOT just the Mag Guard MCP.
The best crosses for legacy KA type MCPs to PowerpacT MCPs are as follows:
KAP . . . crosses to JJP . . . or HJP . . .
KAP . . . MT crosses to JJM . . . or HJM . . .
KAF . . . crosses to JJF . . . or HJF . . .
Existing handle operators will not work on the replacement breakers. For MCC applications, a new bucket will be required.
