Footnotes

  1. Can be used on 3Ø3W Delta voltage systems (for example, 240 V Delta or 480 V Delta).
  2. QMB/QMJ fusible switches, maximum 400 A, SCCR based on Class J, R, or T fuses. QMB plug-in circuit breaker rating is equal to the lowest rating of the circuit breaker.
  3. Multiple mains—provisions for mounting 30 inches of fusible devices. No more than six main devices permitted per NEC.
