£263.88
The Lovato DM38T2500 is a robust solid-core current transformer for busbar applications, designed to convert high primary currents into a standard secondary current for electrical measurement and monitoring equipment. Part of the Lovato DM38 current transformer range, it provides a transformation ratio of 2500/5 A for high-current industrial power distribution systems.
Designed for installation around 64 × 64 mm busbars, the DM38T2500 is well suited to switchboards, distribution panels and industrial electrical systems where dependable current measurement is required. It provides a burden of 20 VA at accuracy class 0.5, supporting integration with compatible metering and monitoring instruments.
The transformer operates at 50–60 Hz and provides a standard 5 A secondary output. With screw terminals, IP20 protection and mounting by either DIN rail or screw fixing, the DM38T2500 offers a practical solution for high-current busbar monitoring installations.
Current transformers reduce a high primary conductor current to a proportional secondary current that can be safely used by compatible measuring and monitoring equipment. The Lovato DM38T2500 converts a nominal 2500 A primary current to 5 A secondary current, allowing high-current circuits to be monitored without routing the full line current through the measuring instrument.
The solid-core DM38 design is intended for busbar installations and accommodates a 64 × 64 mm busbar. Its class 0.5 measurement capability, standard 5 A output and flexible mounting options make it suitable for integration with compatible ammeters, multimeters, energy meters and monitoring equipment in industrial switchboards.
