What are the catalog numbers and purpose for wire harnesses for Powerpact H, J, and L frame circuit breakers?
Issue:
What is the purpose of optional wiring harnesses in the Powerpact H Frame, J Frame and L Frame breakers in both Unit Mount and ILINE applications, and what are the catalog numbers?

Product Line:
Powerpact H Frame, Powerpact J Frame, and Powerpact L Frame

Resolution:
The wiring harnesses for the H, J, and L Frame breakers allows the accessory wiring to exit the circuit breaker through wiring channels in the side of the circuit breakers. This feature is especially important in I-line application because I-line bussing restricts the control wire from coming out the top of the breaker.  I-line wire harness is included as standard for communication network accessories. Wire harnesses may also be used for unit mount applications.
