NK CTRC-333-1000-24U-D - AC Current Transformer, CTRC Series; 1000 A AC

• Output Type = 333 mVAC
• Full Scale Range = 1000 A AC
• Power Supply = 24 VAC or DC
• Case Style = DIN rail mounting

CTRC AC Current Transformers monitor circuits up to 2000 A and produce a safe, low voltage output proportional to the RMS current value. This output is designed as an input to a power monitor or transducer, replicating the AC wave shape with phase angle resolution better than 2 degrees. The flexible coil design allows the sensor to be installed over multiple conductors or bus assemblies easily. The cable requires very little space to fit between adjacent phase conductors. The design eliminates the magnetically permeable core of standard current transformers while providing excellent isolation, sensing only the magnetic field of the phase inside the loop.
