Measurement current transformers

The Series 27 range of measurement current transformers is available in six window sizes with hole diameters from 32 to 112 mm and ratings from 20 to 3000 A to suit a range of applications from panel metering to energy management input.

The current transformers can be mounted using the feet provided, or busbar mounted using the busbar kits for either bar or cable mounting in various types of switchboards.

The Series 27 complements other current transformers including the Series 30 busbar mount current transformers, Series 25 epoxy encapsulated measurement current transformers for challenging environmental conditions and Series 29 Split Core current transformers for existing installations where downtime or cost does not permit dismantling bars or cables to fit conventional current transformers.
