J&D’s New product will be launched at the upcoming trade show, 2015 Hannover Messe (#G19)

The New Remote 3&1 CT
Miniature 3&1 current transformers are suitable for primary ranges from 30A to 630A with 0.1A, 333mV AC secondary.
3&1 phase current transformers built-in RJ12 can be used in combination at directly bus-bar or cable of branch circuit power meter with easy installation and saving cost.
Also it enables more accurate measurement & calibration parameters with RJ12 and they are designed with the combined use for both panel and DIN rail mounting.
