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

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

Main technical specifications

• Primary rated current: 1200 A

• Secondary current: 5 A

• Rated burden (secondary): 15 VA

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

• Mounting / internal diameter: for busbars 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 standard 5 A secondary current. This conversion allows safe connection of measuring and monitoring devices without the need to route power conductors directly through the measuring equipment.

It is suitable for:

• distribution systems in residential, commercial and industrial facilities,

• load measurement and control systems,

• connecting measuring equipment, ammeters and power meters,

• protection and automation systems,

• cases requiring compact installation on an 80 mm busbar.

Product advantages

• High current capacity up to 1200 A

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

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

• 15 VA rated burden - suitable for many common measuring instruments

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

• Versatile use in measurement, protection, automation and monitoring applications
