Description
Description
Introduce
 
DM series current transformers can be used to test, control, display and record the operation of electrical equipment and protect the equipment from damage.
DM can also be used in matching mine transformers.
 
Applications
Current measurement, monitoring and piotection for electrical wiring and equipment.
Current and power measurement for electric motors, lighting,air compressor, heating and ventilation system.
Air-condition equipment and Current, power and energy monitoring device.
Relay protection device.
Features
The DM series of current transfomer are convenient for mounting in many ways. 
The most current transformer need the special mounting and the DM series used，the mounting of DIN typing without a lot of time. 
The protective cover for the terminal block used the switching device with safety and quick
AC circuit. Two built in fixing methods: DIN rail; Busbar mounting.
Compact design .Built in hinged terminal cover .
Primary current from 15A to 300A.
