[2] The standard rating plug supplied with a trip unit will be the “A” rating plug. To specify an alternative adjustable rating plug, please add the letter designation to the end of the catalog number. Please refer to page 7-64 for a complete listing of adjustable settings available with each plug. (Example: S143B would specify a “B” rating plug instead of the standard "A" plug.) Use suffix “N” if no rating plug is required, deduct. [3] When replacing a standard trip unit with Type A (Ammeter), P (Power metering) or H (Harmonic analysis) trip unit, order the 12-pin connector kit S33101 for the MasterPact NW and NT and the PowerPacT P-frame drawout circuit breakers or kit S33100 for PowerPacT P-frame and R-frame unit-mount and I-Line circuit breakers. See page 7-64. [4] Requires Circuit Breaker Communications Module. [5] Requires neutral current transformer in 3Ø4W systems. [6] Alarm history is available through the trip unit display and communications. Local indication of an alarm requires an M2C Programmable Contact Module.
