Why Choose the Lovato DM1TMA0250 Compact Split-Core Current Transformer?
The Lovato DM1TMA0250 is a compact split-core current transformer designed for accurate current measurement in industrial and commercial electrical installations. Featuring a 250/5 A transformation ratio, it converts high primary currents into a standard 5 A secondary output for connection to energy meters, multifunction measuring instruments, power analysers and protection devices.
Its split-core construction allows installation around existing conductors without disconnecting the primary circuit, making it an excellent choice for retrofit energy monitoring, switchboard upgrades and preventative maintenance projects. This reduces installation time while minimising disruption to operational equipment.
The DM1TMA0250 features a compact housing with a 24 × 24 mm internal opening and is supplied complete with a 2 m prewired secondary cable for straightforward installation. Operating at 50/60 Hz with Class 1 accuracy and a 1 VA rated burden, it delivers dependable performance for electrical monitoring and energy management applications.
