To order, replace the CTML-0350 part number suffix “-xxx” with one of the available Rated Amps values. For example: CTML-0350-050. The “Max. Amps” is the highest continuous current that the CT can withstand without damage. The “Max Wire Gauge” is the largest wire gauge that should fit through this size of CT. Available Models: CTML-0350-005, CTML-0350-020, CTML-0350-050, CTML-0350-070
