First you need to define the type of current transformer, of which we offer three types.
- Solid CT
- Bolt on CT
- Split Core CT
For more information on solid CT , then check the attached Acti9 catalogue in which you can find in section 7 Control and command page 98 to page 108.
For more information on bolt on CT which is the direct connected Ct,s that fit to the NSX MCCB, the attached document Section 8 Powerpact 4 Panelboards, page 17 of the Acti9 catalogue.
Two options are available as listed below, one is with voltage references and the other is without
The factors to take into account here are the amount of available space in the MCCB panel, current to be measured and how many poles are required to be monitored. If this method is used then there are two types of facility that the Ct can offer see diagram below.
For the Split Core CTs see attached the Veris split core CT sheet showing various sizes referring to current ratio.
