DM34T1600 Lovato CURRENT TRANSFORMER 1600/5A FOR D44MM C

Why Choose the Lovato DM34T1600 1600/5 A Current Transformer?

The Lovato DM34T1600 is a solid-core current transformer designed for high-current electrical metering and monitoring applications. With a rated primary current of 1600 A and a standard 5 A secondary output, it provides a 1600/5 A transformation ratio for compatible energy meters, power analysers, ammeters and electrical monitoring equipment.

The DM34T1600 features a 44 mm cable aperture and is also designed for 69 × 10 mm and 50 × 30 mm busbars. This combination makes it suitable for high-current switchboards and distribution systems where either large cables or rectangular busbars are used as the primary conductor.

Designed for 50–60 Hz systems, the DM34T1600 provides 5 VA at Class 0.5 and 15 VA at Class 1. It also features a 720 V rated insulation voltage, 120% continuous overload withstand, screw terminals and DIN rail or screw fixing for dependable integration into industrial and commercial electrical panels.

Accurate High-Current Measurement for Cables and Busbars

A current transformer converts a high primary current into a proportional secondary current that can be measured by compatible instrumentation. With the DM34T1600, a rated primary current of 1600 A corresponds to a standard 5 A secondary current, allowing meters and power analysers to monitor the electrical circuit without carrying the full primary load current through the measuring device.

The solid-core DM34T1600 can accommodate a cable through its 44 mm aperture or compatible 69 × 10 mm and 50 × 30 mm busbars. When installed with a busbar, the busbar should be positioned centrally within the transformer opening. This configuration provides a practical measurement solution for high-current distribution boards, switchboards, energy-management systems and power-monitoring installations.

Typical Applications

• High-current energy metering installations.
• Industrial switchboards and distribution panels.
• Commercial building electrical distribution.
• Power analyser current inputs.
• Electrical load and consumption monitoring.
• Energy management and sub-metering systems.
• Large cable and busbar current measurement.
• Electrical circuits with primary currents up to 1600 A.
