GE Spectra RMS™ Circuit Breakers Electric machine

GE Spectra RMS™ Circuit Breakers Electric machine

DESCRIPTION

These breakers are available only with interchangeable trip units. Two frame sizes are available, the 800 ampere frame (300 to 800 amperes) and the 1200 ampere frame (600 to 1200 amperes). Trip units are not interchangeable between frames. "Complete Circuit Breaker" price includes frame, trip, Cu/AI line, and load lugs. Units will be shipped unassembled unless specified "must be factory assembled." If line lugs are not required on the breaker, eliminate "WL" from catalog number and subtract price of line lugs.

How To Order:

• Determine the required breaker frame (i.e., 150, 400, 600, 800, or 1200 amperes), 1C rating, and load requirements (UL Standard or 100%). Determine overcurrent protective functions (LI, LSI, LIG, LSIG). Select frame catalog number and list price from table on page 4-27. 

• Select and price the required rating plug from table below. The sensor rating of frame must match the sensor rating of the rating plug in table. 

• Select and price lugs and lug covers as required from page 4-63. 

• Select and price appropriate combination of Distribution Cable System accessories from pages 4-32 to 4-34. 

• Select and price any other accessories from page 4-35 and 4-47 to 4-65. 

• When ordering, specify separate catalog numbers as follows: 

—Frame 

—Rating Plug 

—Lugs 

—Distribution Cable Accessories 

—Other Accessories
