IA60B31K – Current Transformer Flexible, compact and reliable, those are the keywords of the IA-series of ELEQ. All transformers are equipped with a sealable integrated terminal cover. These very accurate current transformers are suitable for measurement and for revenue metering (billing). The accuracy is guaranteed from 0,1VA upwards. Therefor there is no need of using load resistors. For revenue metering: the serial number shown on the product is linked with unique measuring data available on our website. ELEQ provides isolated mounting clips which makes the IA-series suitable for mounting on rail or around cables.
