Product catalog summary

Contact Information: DENT Instruments, Inc. is located at 925 SW Emkay Drive, Bend, Oregon 97702 USA. They can be contacted via phone at 541.388.4774 or 800.388.0770, and their website is www.DENTinstruments.com.

Key Specifications: The current transformers have a window size of 25mm (1.0”) and a current range of 1 - 300 A AC. The output is 333 mV at 200 A AC, with a ratio error of less than 1.0% and a phase error of less than 0.5° from 1.0 A to 300 A AC.

Mechanical Specifications: The case material is white nylon, UL 94 V-0 rated. The leads are 2.4 meters (8 feet) long, 600V, 22 gauge. The operating temperature range is -15 to 60°C (5 to 140°F), and the storage temperature range is -20 to 85°C (-4 to 185°F).

Part Numbers: Two part numbers are specified: CT-HMC-0200-U with crimp ferrules on leads, and CT-HMC-0200-B with 4mm banana plugs.

Electrical Specifications: The output is 333 mV at 200 A. Wire polarity is indicated as white for high, positive (+) and black for low, negative (-). The phasing orientation is marked with an arrow on the case pointing toward the load. The frequency range is 50 to 400 Hz.

Safety Standards: The working voltage is 600 VAC, Category III, with a dielectric strength of 5200 VAC for 1 minute. The safety standards include UL STD 61010-1 and CAN/CSA STD C22.2 No. 61010-1.

Product Description: The high-performance MIDI hinged current transformers are designed for medium amperage applications. They are suitable for current measurement, energy metering, load surveys, demand metering, energy research, and submetering.

Performance Graph: A graph illustrates the ratio error and phase error across the CT primary current range from 0 to 300 Amps, showing minimal errors within the specified range.
