Indoor

3.6- 7.2 - 12 - 17.5 -24 - 36 KV

Primary current from 0 to 3000 A

Ith up to 1000 Ipn or 100 KA/1s

Compact size

Cast-resin insulated

Low level of partial discharges

Up to 5 cores

Screw-in connectors

Current transformers vacuum moulded in self-extinguishing epoxy resin for the measurement of AC currents up to 3000A.

This comprehensive and compact range of current transformers has been designed to meet the requirements of MV switchgear manufactures.

It offers a very low level of partial discharges and up to 5 separate cores. It allows double-ratio up to 600-3000A.
