1If Product No. digit “K” is selected from Full Load Current Selection Table, deduct $55.00 from list price.
2Reset on CR324FX*S overloads is approximately 1” longer than on equivalent bimetal overloads. For GE 300-Line enclosures, perform the actions noted below:
Enclosure Reset Extension Type Adjustment Required
Threaded Rod (standard) Cut threaded shaft 1” and adjust for 1/8” gap.
“U” Style, 2 1/8” long Replace extension with product number 55-512811G005.
“U” Style, 1 1/2” long Replace extension with product number 55-512811G002.
3CR324GX*S may be used as replacement for bimetal overload on size 5 starters. Use existing CTs.
4CR324HX*K kit must be used as solid-state replacement for bimetal overloads on size 6, since CT ratio changes, CTs included.
5CR324HX*S may be used as a replacement for existing solid-state overload on size 6. Use existing CTs.

Full Load Current Selection Table
For continuous rated motors, with a service factor of 1.15 to 1.25, select the heater with maximum motor Amperes equal to or imme-
diately greater than the motor full-load current (provides a maximum of 125 percent protection). For continuous rated motors with no
service factor, multiply the full-load current of the motor by 0.90 and use this value to select the heater.
