DM… are instrument transformers in class 1/0.5 without a primary winding and are normally used for high primary current values starting from 50A. The number of loops of the primary cable does not modify the accuracy but converts the primary current value proportional to secondary current.

Operational Characteristics:

Operating frequency: 50-60Hz.
Secondary output current: 5A.
Overload withstand: 120% Ipn.
IEC rated insulation voltage UI: 720V.
Insulation (dry tape): Class E.
Terminals: Faston for DM2T and DM3T types; Screw for DM0T, DM4T and DM5T types.
Sealable terminal covers for DM0T, DM4T and DM35T types.
Fixing on 35mm DIN rail(IEX/EN 60715) or by screws (fixing elements standard supplied with product).
IEC degree of protection: IP30.
Ambient conditions: Operating temperature -25…+50 degrees Celsius; Storage temperature -40…+80 degrees Celsius; Relative humidity, non-condensing 90%.
