DM series of current transformer can be applied to test, control, display and record the running of the electrical equipment, and to protect the equipment against the damage, in the AC circuit with the rated voltage value below 660V and the frequency of 50 - 60Hz. DM can be also applied to form a complete set of mine Transformer.
Feature:
1:AC circuit
2:Two built in fixing methods: DIN rail; Busbar mounting
3:Built in hinged terminal cover
4:Compact design
5:Primary current from 15A to 300A.
6:The DM series of current transfomer are convenient for mounting in many ways.
7:The most current transformer need the special mounting and the DM series used
the mounting of DIN typing without a lot of time.
8:The protective cover for the terminal block used the switching device with safety and quick
