Product details
TR35CT250 is a three-phase current transformer from Terasaki's Resilience metering range, with a 35 mm window, a 250 A primary rating and a 330 mV output. Terasaki lists it for both Resilience Standard and Resilience Plus panel boards.
Key features
- 250 A primary, 330 mV output
- 35 mm window
- Three-phase
- The highest-rated CT in Terasaki's Resilience Plus outgoing meter chart
- Connects to the meter with an RJ45 CT cable
Typical applications
Metering a 250 A outgoing way on a Resilience Plus board, where 250AF ways take MCCBs up to 250 A, read by a single-channel panel meter (TRSSMP1, or TRSSMMP1 for MID). On Resilience Standard it appears among the loose metering items next to the 25 mm and 45 mm CTs. As a 330 mV CT it needs a meter designed for that input, not a 1 A or 5 A meter.
On a Resilience Plus board each outgoing meter takes one CT, one TRRJ45CC05 cable and one single-channel meter, mounted in a side cableway with a cableway metering door kit. Our Panel Builder picks the CT from the rating of the MCCB on each metered way.
