ONKA TK8012005309 - Plug-in current transformer 1200/5 A (15 VA, class 0.5S)

The ONKA TK8012005309 current transformer is a high-quality plug-in transformer designed for indirect measurement of sinusoidal alternating current in electrical switchboards, panels, and professional measurement systems. Its robust construction and accurate measurement class make it suitable for demanding industrial and commercial applications.

Main technical specifications

• Primary rated current: 1200 A

• Secondary current: 5 A

• Rated load (secondary): 15 VA

• Accuracy class: 0.5S - high accuracy for load measurement and monitoring

• Mounting/internal diameter: for rails Ø 80 mm

• Mounting feet: included - allows installation without interrupting the power circuit

Purpose and use

The transformer converts a high primary current of up to 1200 A into a standardized secondary current of 5 A. This conversion allows safe connection to measuring and monitoring instruments without the supply cables having to run directly through the measuring equipment.

It is suitable for:

• residential, commercial, and industrial switching equipment,

• load measurement and control systems,

• connection of measuring equipment, ammeters, and power meters,

• security and automation systems,

• applications where compact mounting on an 80 mm rail is required.

Product advantages

• High current capacity up to 1200 A

• Standard 5 A output - wide compatibility with measurement and control systems

• Accuracy class 0.5S - stable and reliable measurement for billing or industrial monitoring

• Rated load 15 VA - suitable for the most common measuring instruments

• Easy installation thanks to snap-on design and mounting feet

• Versatile use in measurement, security, automation, and monitoring
