LOW COST 50/60 Hz CURRENT SENSORS
This series of current sensors offers standard accuracy
at low cost. The molded aperture is a PC mountable
design made to meet IEC 360 and other safety agency
requirements when used with an insulated conductor.
These 50/60 cycle CT’s are capable of current ranges
up to 200 Amps. Variations of this standard product can
be accommodated.
