Chint BH-0.66 30I 200/5
Chint BH-0.66 30I is a solid-core low-voltage current transformer, supplied wound 200/5 A in accuracy class 0.5S: the CT that puts a DTSU666-CT meter on a 200 A three-phase incomer.
- 200/5 A ratio at Class 0.5S accuracy, 5 VA rated burden, 5 A secondary for standard meter/relay wiring.
- Compact 80 × 60.5 × 33 mm housing, mounts to plate or busbar in any orientation.

The meter is only as good as its CTs.
Matched-class current transformers keep the measurement chain inside its accuracy class.
200/5 A, Class 0.5S
Wound ratio 200/5 A at 5 VA burden, accuracy class 0.5S - matched to the DTSU666-CT meter class. Other ratios of the BH-0.66 family are available on request.
Inspect it before you spec it.

Chint DTSU666-CT smart meter
- [1]Chint DTSU666-CT smart meter
Configuration 1
Yes, that is the pairing this listing is built around: the 5 A secondary feeds the meter's external-CT input and the accuracy classes match.
- Ratio: 200 A primary to 5 A secondary, wound, single primary turn.
- Accuracy: Class 0.5S at the rated 5 VA burden per Chint's data, matched to the DTSU666-CT meter class.
- Commissioning: the meter is set to the 200/5 ratio during commissioning.
Availability & compliance 2
Yes. The BH-0.66 family covers ratios from 30/5 to 4000/5 across several window sizes; this listing is the 30I frame wound at 200/5 with a 23 mm window.
- Window check: the 23 mm round window takes the phase conductor of a typical 200 A feed; larger conductors need a larger frame from the same family.
- Ordering: request the ratio and window size you need with your quote and we source it with the meter.
- Standard: the family are low-voltage instrument transformers to IEC 61869-2.
The BH-0.66 30I is a low-voltage current transformer to IEC 61869-2, rated 660 V at 50/60 Hz.
- Class: 0.5S for the 200/5 winding at 5 VA rated burden, per Chint's data.
- Metering chain: the CT class is specified to match the DTSU666-CT meter class, so the metering point keeps its rated accuracy.
- Documentation: confirm the certificate set your application requires with the quote.
Installation & wiring 1
Three, one per phase, wired to the meter's 1.5(6) A secondary input terminals.
- Fitting: solid core, so the phase conductor is routed through the 23 mm window; plan the fit at a point where the conductor can be taken through.
- Mounting: 80 x 60.5 x 33 mm housing, fixed to a plate or busbar in any orientation.
- Site limits: -5 to +40 C, below 80 percent RH, up to 1000 m altitude, on 660 V-class low-voltage circuits at 50/60 Hz.
