Terminations

Position three of the catalog number indicates the general lug configuration of the circuit breaker. PowerPacT Q-frame circuit breakers have box-type lugs suitable for use with 4 AWG–300 kcmil (21–150 mm²) aluminum or copper conductors. The 250 A circuit breaker allows copper conductors only.

• A = I-Line shroud on ON (I) end

• L = Lugs on both ends

• P = Lugs on OFF (O) end only

• E = I-Line bolt-on configuration

• M = Lugs on ON (I) end only

• F = No lugs (bus connection)

Special terminal arrangements may be called out in the catalog number by adding a two-digit code following the ampere rating. The first digit of the special terminal code is always the letter “T”.

• TS = Studs on both ends (no nuts or washers)

• TN = Studs on OFF (O) end only (no nuts or washers)

• TP = Studs on ON (I) one only (no nuts or washers)

• TM = Studs on ON (I) end with nuts and washers

Circuit breakers with control taps are identified in the catalog number through a two-digit code in the suffix. The first digit of the control tap code is always the letter “L”.

• LU = Control taps applied to ON (I) end

• LV = Control taps applied to OFF (O) end

• LW = Control taps applied to both ends

Circuit breakers with special features are identified in the catalog number with a two-digit code following the ampere rating. The first digit of the special feature code is always the letter “Y”.

• YD = Calibration test report supplied

• YF = Fungus treatment

• YP = Handle padlock attachment, OFF (O) or ON (I) position

• YQ = Handle padlock attachment, OFF (O) position only

Other special terminations and special features are available. Contact the local Field Sales office for more information.

When multiple options are required, they should be applied in the following order:

C—50°C (122°F) ambient

T—Special terminations

L—Lug options

Y—Special options
