Product details
TR45CT400 is a three-phase current transformer (CT) with a 45 mm window, rated 400 A primary with a 330 mV output. It is the largest of the three CTs Terasaki lists for Resilience Standard panel boards, alongside the 25 mm and 35 mm types.
Key features
- 400 A primary rating, 330 mV output
- 45 mm window, the largest in the Resilience Standard list
- Three-phase
- Connects to its meter with an RJ45 CT cable
Typical applications
Metering at the 400 A level, which is the rating of the larger Resilience Standard board and its incomer, and replacing a CT on metered installations. Pair it with a meter designed for 330 mV CT inputs: it gives a low-voltage signal, not the 1 A or 5 A secondary current of a conventional CT, so it should not be wired to a meter that expects one.
Listed with the Resilience Standard metering items. For incoming metering of a new 400 A Resilience Standard board, the complete kits TRS400MK (standard) and TRS400MKM (MID) come with their own meter and CT.
