More information

CT Type: Solid-Core

Amperage: 200 amps

Inside Diameter: 25 mm or 0.98 inches

Outside Diameter: 56 mm or 2.20 inches

Thickness: 20 mm or 0.80 inches

Model: BCT-025-200UL

Certifications: CE, Approved by UL for use with our UL Listed Omnimeters

Wire Gauge: For use on cable that is 400 MCM or smaller. It is best to measure your wire diameter in millimeters, rather than use the MCM wire size. This is because the insulation thickness varies materially from one wire manufacturer to the next. It is much better to oversize your CT than to undersize it.

Designed for accuracy and economy. These CTs, when combined with our Omnimeter models, provide revenue-grade accuracy.

These CTs are extremely accurate down to a few watts with a degree of precision of 0.1%. They have 7518 internal turns, creating a 26.6mA output at full amperage. Use these CTs for any system from under 1/4 amp to 200 amps.

You can pass multiple wires from the same phase through this CT. As long as the wires are passing in the same direction and are on the same phase, our CTs will measure their combined current accurately.

  • Use 1 CT for 120 volt single phase North American, or 230 volt 2-wire foreign systems
  • Use 2 CTs for 120/240 volt single phase systems
  • Use 2 CTs for 3-phase 3-wire systems (no neutral)
  • Use 3 CTs for 3-phase 4-wire systems

These CTs include black and white wire leads that are 6 feet in length.

UL approved for use in concert with our UL listed meters to be a complete UL listed install.

Each current transformer has a unique serial number, is individually tested, and indicates the correct orientation of the CT in relation to the load of the electrical system being metered.

Ask a Question
  • Do these have an internal burden resistor?

    The current transformers we carry do not have the burden resistor inside of the CT.  The burden resistor is inside of the Omnimeter.  We use a 5.1 Ohm burden resistor inside of the Omnimeter.

  • Is the output on this CT 26.6ma AC or DC?

    All of our CTs have a 26.6mA AC output.  This is an AC signal that proportionally matches the "current/amps" sine wave of the primary wire.  For example if you are using a 200 amp CT and you have 200 amps in the primary wire, the CT will put out 26.6mA of AC current.
