CBT Current Transformer Metering 0.6 kV
CBT/1 and CBT-H
600 volt, indoor/outdoor, 10 kV BIL, primary amperes: 100-800 25-60 Hz.
CBT-S
600 volt, indoor/outdoor, 10 kV BIL, primary amperes: 600, class: 0.15S B-0.2 (IEEE 0.15S class metering accuracy) 60 Hz.
The CBT-S bar-type current transformer is designed for use in metering 600 volt circuits, typically installed inside of a transocket. Applicable to single or polyphase low voltage circuits, a single 600:5 ratio unit will perform at the 0.15S metering class from 30A -1200A for extended range metering. The CBT-S is part of ABB’s AccuRange® current transformer portfolio, high accuracy transformers that reduce inventory requirements and significantly improve metering accuracy.
