Why Choose the Lovato DM39T3000 Current Transformer?
The Lovato DM39T3000 is a 3000/5 A current transformer designed for current measurement in high-current low-voltage electrical installations. It converts a primary current of up to 3000 A into a standard 5 A secondary signal for compatible measuring instruments, power analysers and protection equipment.
Part of the Lovato DM current transformer range, the DM39T3000 features a large 102 × 55.5 mm busbar aperture, making it suitable for installation around substantial conductors and busbars in industrial switchboards and power-distribution assemblies.
By providing galvanic separation between the high-current primary circuit and connected measuring equipment, the DM39T3000 enables practical indirect current measurement in applications where direct connection to the primary circuit would be unsuitable.
Key Advantages
- High 3000 A primary current rating for substantial power-distribution circuits.
- Standard 5 A secondary output for compatible meters and measuring equipment.
- 3000/5 A transformation ratio enables indirect measurement of high currents.
- Large 102 × 55.5 mm aperture accommodates substantial busbars and conductors.
- Provides electrical isolation between the primary circuit and measurement equipment.
- Suitable for industrial switchboards, distribution systems and power-monitoring applications.
Key Features
- Lovato DM current transformer range.
- 3000/5 A current transformation ratio.
- 3000 A rated primary current.
- 5 A rated secondary current.
- 102 × 55.5 mm rectangular aperture.
- Designed for indirect AC current measurement.
- Suitable for use with compatible digital meters, power analysers and measuring systems.
- Designed for installation in industrial electrical distribution assemblies.
Reliable High-Current Measurement
Accurate monitoring of high-current circuits requires a current transformer matched to both the conductor arrangement and measuring equipment. The Lovato DM39T3000 scales a primary current of up to 3000 A to a conventional 5 A secondary current, allowing compatible instruments to monitor substantial electrical loads without carrying the full primary current through the meter.
Its generous 102 × 55.5 mm aperture is particularly useful in switchboards and distribution assemblies employing large busbars. This makes the DM39T3000 a practical measurement component for industrial power monitoring, energy management and electrical instrumentation systems.
Typical Applications
- High-current industrial switchboards.
- Main low-voltage distribution panels.
- Busbar current measurement.
- Digital multimeter installations.
- Power analyser and monitoring systems.
- Energy-management systems.
- Industrial plant electrical monitoring.
- OEM power-distribution equipment.
