2.4.2 CTs Dimensions and Terminal Definitions
There are multiple types of CTs available for the Mains Input, or DC Residual Current Input and Branch
Inputs. It’s extremely important for the users to understand that the Hall Effect Split-Core CTs and DC
Residual CT for the Mains Input have a Voltage Output while the Hall Effect CTs for the Branch Circuits
have a Current Output. Caution should be exercised during the installation of the Hall Effect CTs for the
Mains and Branch Inputs. Using incorrect CTs for the Mains and Branch Inputs may cause permanent
damage to the PMC-512-D. Please refer to
Appendix C
for their complete specifications and select the
appropriate CTs for your applications.
The following figures describe the dimensions for the various CTs and the definitions for their terminals.
