CTT0550 Toroidal Current Transformer, Motor Protection
The CTT0550 series of panel mounted, toroidal, solid-core current transformers offers exceptional signal transformation accuracy with minimal phase shift. Designed for applications where the AC primary current must be transformed into a lower AC current or AC voltage signal appropriate for micro-processor based circuitry while exposed to harsh environmental operating conditions.
Secondary AC current option:
||Rated Primary Current
||100A to 800A
||AC current option: Winding ratio options:
1:1000, 1:2000, 1:3000 or 1:5000
|0.1, 0.2, 0.5 (IEC 60044-1)
|AC voltage option: Any value between 0.333VAC and 7.07VAC
- Accuracy Class achieved is dependent upon external VA secondary burden.
- The secondary output @ rated current is dependent upon the ratio selected.
