100A Midi Hinged CT

Product catalog summary

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

Part Numbers
Two part numbers are specified: CT-HMC-0100-U with crimp ferrules on leads, and CT-HMC-0100-B with 4mm banana plugs.

Electrical Specifications
The output is 333 mV at 100 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 from 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.

High Performance Midi Hinged Current Transformers
These transformers are designed for high performance and medium amperage applications, suitable for current measurement, energy metering, load surveys, demand metering, energy research, and submetering. The window size is 25 mm (1.0 inch), with a current range of 1 - 200A AC. The output is 333 mV at 100 A AC or 3.33 mV/A AC. The ratio error is less than 0.3% from 1.0 A to 200 A AC, and the phase error is less than 0.5° from 1.0 A to 200 A AC.

Graphical Data
The document includes a graph showing the ratio error and phase error across the CT primary current range from 0 to 200 Amps, indicating performance consistency within specified limits.
