Lovato DM1TA0500 split-core current transformer with a 500/5 A ratio, 52 x 80 mm opening, Class 0.5 accuracy at 2.5 VA and Class 1 accuracy at 5 VA for electrical metering and energy monitoring.
£114.65
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.
The Lovato DM1TA0500 can be opened and fitted around an existing conductor, allowing energy-monitoring equipment to be added without removing cable terminations or passing the conductor through a closed transformer aperture. This helps reduce installation time and minimise disruption to operational electrical systems.
Its standard 5 A secondary output is compatible with a broad range of multifunction meters and power analysers. The generous rectangular opening accommodates substantial cables and busbars, while the available accuracy and burden ratings support both precision metering and general electrical monitoring.
