The Lovato DM1TP0400 is a precision solid-core current transformer designed for industrial electrical metering, power analysis and energy-monitoring applications. It provides a 400/5 A transformation ratio, converting a rated 400 A primary current into a standard 5 A secondary signal for compatible meters and measuring instruments.
Designed for cables up to Ø28 mm, the DM1TP0400 can also accommodate 30 × 10 mm, 25 × 15 mm and 20 × 20 mm busbars. Its precision metering performance includes Class 0.5S at 5 VA and Class 0.5 at 5 VA, making it well suited to accurate electrical consumption and load measurement.
The transformer operates on 50–60 Hz AC systems and combines screw terminals with DIN rail or screw mounting for flexible panel installation. A 720 V rated insulation voltage, Class E dry-type insulation and IP30 protection support dependable operation in industrial switchboards and electrical distribution equipment.
The Lovato DM1TP0400 enables compatible measuring instruments to monitor high AC currents by converting a rated 400 A primary current into a proportional 5 A secondary signal. Its Class 0.5S performance makes it particularly suitable for installations where accurate current and energy measurement is required.
The solid-core construction provides a robust solution for new switchboard installations, while the Ø28 mm opening and compatibility with several common busbar dimensions offer useful installation flexibility. DIN rail or screw mounting and standard screw terminals further simplify integration with industrial metering equipment.

The DM1TP0400 is a solid-core current transformer designed to convert a rated 400 A primary current into a standard 5 A secondary signal for compatible energy meters, multimeters and power analyzers.
The Lovato DM1TP0400 has a 400/5 A transformation ratio, providing a 5 A secondary output at its rated 400 A primary current.
The transformer is designed for cables up to Ø28 mm and can also accommodate 30 × 10 mm, 25 × 15 mm and 20 × 20 mm busbars.
The DM1TP0400 provides Class 0.5S accuracy at 5 VA and Class 0.5 accuracy at 5 VA.
The transformer supports DIN rail or screw fixing and uses screw terminals for the secondary connection. As a solid-core transformer, the primary conductor or busbar must pass through the transformer opening during installation.
Lovato Electric current transformers provide accurate current sensing for energy meters, power analyzers and electrical monitoring systems, combining precision measurement with practical mounting options for industrial and commercial power-distribution installations.
