“SARAH Inc.” AC Current Sensor (Current Transformer) High-precision, Cramp-on Type

SARAH Inc.: AC Current Sensor High-precision, Cramp-on Type (Through Hole dia: For 10 mm dia. & 16 mm dia. Cable)

SARAH Inc. SR-3700 Series, SR-3800 Series
■ Features:
1) CT are attached to a cable easily by clamp-on structure.
2) The ferrite core reduced misalignment between top coa & bottom coa by our original structure and improved performance.
3) When pulled the lead wire, the lead wire do not fall out by the prevention structure of pull force.
4) Our CT is production in Philippine (Cebu factory). Threfore, our CT becames low price.
5) Compliant with RoHS.
■ Applications:
Monitoring system of electric energy (Home, Industry, Data center etc.) and others .
