NewTrend · PR-5P20
Product overview
NewTrend PR-5P20 protection current transformers with5A secondary and15VA rated burden. Select a proven ratio; the bore and outer dimensions follow the exact row.
Technical selection summary
| Parameter | Specification |
|---|---|
| Construction | Tape-insulated toroidal protection current transformer; not an autotransformer or10kVA power transformer |
| Accuracy / burden | 5P20 at15VA rated burden for the exact retained PR-5P20 table |
| Secondary | 5A; exact primary ratios in the linked list |
| Meaning of5P20 | Composite error limit5% at accuracy-limit current20 times rated primary, at rated burden and stated conditions; not a universal no-saturation threshold |
| Polarity | P1/P2 primary and S1/S2 secondary markings retained in actual NewTrend photograph |
| Other classes | 5P10/10P10 sample tables are retained as separate reference constructions, not automatically mixed with these5P20 dimensions |
| Safety | Never open-circuit an energised current-transformer secondary; use the supplied installation instructions |
The5P20 matrix and actual2500/5A15VA nameplate govern the selectable configuration. Other protection classes need their own ratio/burden/dimension pairing; no arbitrary5P/10P class substitution is made.
