Lovato DM2TA0300 - CURRENT TRANSFORMER - SPLIT-CORE - FOR 80X80MM BUSBARS - 300A

General characteristics

The DM...TA type current transformers (CTs) are installed in an electrical system to reduce the line current to a secondary value of 5A compatible with the ammeter inputs of the digital multimeters or protection relays.
DM...TA are instrument transformers in class 0.5/1 without a primary winding and are normally used for high primary current values starting from 250A.
