What parts are needed to upgrade a PowerPact P or R frame breaker from a standard trip unit to a Micrologic 3.0A 5.0P 6.0P 5.0H or 6.0H?


Issue:
What parts are needed to upgrade a PowerPact P or R frame breaker from a standard Micrologic trip unit to a Micrologic 3.0A 5.0P 6.0P 5.0H or 6.0H?

Product Line:
PowerPact P and R frame

Environment:
Electrical Distribution Systems

Cause:
A customer may want to increase the functionality of their trip unit

Resolution:
Choose the appropriate trip unit:
3.0A S141A
5.0A S143A
6.0A S144A
5.0P S163A
6.0P S164A
5.0H S173A
6.0H S174A

For R frame and for P frame (excluding motorized, rotary handle, and drawout), they also need the following parts:
Connector S33100
External Voltage Sensing kit S64203 (P and H trip units only, if Voltage sensing is required)
BCM S64205 (if modbus is required)

For P frame drawout, they need the following parts:
Connector S33101
External Voltage Sensing kit S64209 (P and H trip units only, if Voltage sensing is required)
BCM S64206 (if modbus is required)

For P frame motoized, they need the following parts:
Connector S33100
External Voltage Sensing kit S64210 (P and H trip units only, if Voltage sensing is required)
BCM S64207 (if modbus is required)

For P frame with rotary handle, they need the following parts:
Connector S33100
External Voltage Sensing kit S64210 (P and H trip units only, if Voltage sensing is required)
BCM S64205 (if modbus is required)

NOTE:  if upgrading to a 6.0x trip unit (one with ground fault protection) or to a 5.0P/H trip unit used for ground fault alarm) on a 4-wire system (with a neutral) it is also necessary to install a neutral CT.  
Refer to the current edition of Digest section 7 for the appropriate NCT for Powerpact, and to the Masterpact Pricing Guide 0613PL0001 for the appropriate NCT for Masterpact breakers.
