Lovato DM0TW0005 is a 5/5 A wound-primary current transformer with a 5 A secondary output, Class 0.5 and Class 1 metering performance and DIN rail or screw mounting for industrial electrical measurement applications.
£40.04
The Lovato DM0TW0005 is a compact wound-primary current transformer designed for accurate current measurement in industrial electrical metering and monitoring systems. Unlike pass-through current transformers, its wound-primary construction provides dedicated primary and secondary connections, making it suitable for low-primary-current measurement applications.
The DM0TW0005 has a 5 A primary current rating and 5 A secondary output, operating across a frequency range of 50–60 Hz. It provides Class 0.5 performance at 1.5 VA and Class 1 performance at 2.5 VA, supporting accurate measurement with compatible energy meters, digital multimeters and power analyzers.
Designed for straightforward panel installation, the transformer features screw terminals and can be mounted on a DIN rail or by screw fixing. Dry-type Class E insulation, IP30 protection and a 120% continuous primary-current overload withstand make the DM0TW0005 a robust solution for electrical measurement and control applications.
Wound-primary current transformers are particularly useful when the primary current is too low for a conventional single-turn pass-through transformer to provide the required measurement performance. The Lovato DM0TW0005 uses dedicated primary windings to provide a 5 A primary to 5 A secondary current relationship for compatible electrical measuring equipment.
Its Class 0.5 and Class 1 metering performance, standard 5 A secondary output and flexible mounting options make the DM0TW0005 suitable for integration into industrial switchboards, control panels and energy-monitoring systems. Robust insulation and compliance with IEC current-transformer standards support dependable operation in professional electrical installations.
