Three Phase Block Current Transformers

Three Phase Block Current Transformers are basically a number of solid core current transformers housed in one compact block. There are numerous benefits to using a three phase block CT  - they can save space, are easier to install and in some cases are the cheaper option.

If you intend to use a three phase block CT in a low voltage distribution board next to a molded case circuit breaker then be sure to match the pitch of the apertures to that of the cabling on the MCCB.

3 Phase Block Current Transformers are available from 50A > 800A primary in a 5A secondary rating.  If you require other variants please contact us or call us on +44(0)1244 393800 for more details.
