• Motor current setting (thermal) is not specifi ed by NEC/CEC

• MCP breakers are magnetic only

• Thermal capability should be greater than or equal to motor FLA and less than or equal to overload relay setting

• Motor Overload protection must be provided separately

• MCPs are UL Recognized

• Must be tested and listed with specifi c contactors and overloads

• UL Listing is obtained as part of UL 508 Type D combination starters

• Magnetic Trip Current is adjustable

• Adjustability is required by UL489 standard

• Must be sized per NEC/CEC rules – ≤ 800% motor FLA for standard effi ciency motors – ≤ 1300% motor FLA allowed if motor will not start – ≤ 1100% motor FLA for high effi ciency motors – ≤ 1700% motor FLA allowed if motor will not     start

• MCPs are the most popular choice for motor circuits in the North American market

• Used in combination starters and MCC buckets for many years

• Provide choice in overload protection
