Lovato DM1TMA0200 - CURRENT TRANSFORMER - COMPACT PREWIRED SPLIT-CORE - 24X24MM HOLE - 200A

General characteristics

The DM...TMA 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...TMA are instrument transformers in class 1 without a primary winding and are normally used for high primary current values starting from 100A.
