CTML series of mini split-core current transformers (CTs) are ideal for monitoring branch circuits and equipment loads in situations where space is limited. The CTML has an easy to open hinged design that locks closed with a click. The 0.35 inch square window opening can fits one #3 AWG THHN conductor or up to four #12 AWG conductors depending on insulation thickness.

|Model||Opening||Rated Amps (xxx)||Max. Amps||Max. Wire Gauge||MSRP|
|CTML-0350-xxx||0.35″ x 0.35″ 9 mm x 9 mm)||5, 20, 50, 70||150||#3 AWG||$33.00 each|
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
