    What do LU, LV, LW and LZ suffixes mean on PowerPact Circuit Breaker Catalog Numbers?

    Issue:
    What do LU, LV, LW and LZ suffixes on end of PowerPact catalog numbers indicate?

    Product Line:
    PowerPact Molded Case Circuit Breakers

    Environment:
    Applies to all H, J, Q, M and P Frame PowerPact breakers (unit mount and I-line) 
    All PowerPact L frame breakers have tapped lugs as standard.

    Cause:
    When control voltage is required, a common method is to attach the small control wire to the lug on the circuit breaker.

    Resolution:
    These suffixes indicate the breaker includes provisions to attach control wires onto the lugs of the circuit breaker.
    • LU suffix - control wire taps ``ON`` end only
    • LV suffix - control wire taps ``OFF`` end only
    • LW suffix - control wire taps both ends
    • LZ suffix - control wire taps on Left and Center Poles of "OFF" end only
