Why Choose the Lovato DM1TA0500 Split-Core Current Transformer?
The Lovato DM1TA0500 is a dependable split-core current transformer designed for accurate current measurement in industrial and commercial electrical systems. Featuring a 500/5 A transformation ratio, it converts a primary current of 500 A into a standard 5 A secondary signal for compatible multifunction meters, power analysers and energy-monitoring equipment.
Its split-core construction allows the transformer to be opened and installed around an existing cable or busbar without disconnecting the primary conductor. This makes the DM1TA0500 particularly suitable for retrofit monitoring projects, switchboard upgrades and installations where interrupting the electrical supply would be inconvenient or costly.
With a substantial 52 × 80 mm internal opening, Class 0.5 accuracy at 2.5 VA and Class 1 accuracy at 5 VA, the DM1TA0500 provides reliable measurement performance for demanding power distribution applications. Its robust insulated housing, screw terminals and secure fixing arrangement make it a practical choice for professional electrical installations.
