CTT, CTL and CTSC Series from $21
AC Current Transformers
For Ammeters, Wattmeters, Instrumentation, Relays and Energy Management Systems
Current Ratios from 50:5 to 2000:5
UL Recognized and CSA Certified
The CT series current transformers can be used with
meters or any device which needs to have AC current reduced in order to make a measurement. For example, if you need to measure 50 amps AC with an A-D board, you need to reduce the signal first so that it may be conditioned. These current transformers will step down up to 2000 amps to 5 amps. The CTL series is a one-piece current transformer with 24-inch leads. The CTT series one piece current transformer, and CTSC series two piece current transformers use threaded terminals for electrical connections.
The nameplate current ratio of the current transformer is based on the condition that the primary conductor will be passed once through the transformer opening. If necessary, this rating can be reduced in even multiples by looping this conductor two or more times through the opening. The ratio of the current transformer can also be modified by forward or backwinding the secondary lead through the window of the current transformer.
Accuracy is given for the maximum burden as expressed in Volt Amps. The total burden includes the input resistance of the wire and connections between the current transformer and meter.
