£227.97
The ABB TR2 (2CSG060100R1211) is a reliable toroidal current transformer designed for use with residual current monitoring systems in industrial and commercial electrical installations. As part of the ABB TR series, the TR2 provides accurate earth leakage current detection and dependable integration with compatible residual current monitoring relays.
This through-feed current converter features a closed, non-openable toroidal design with screw connection terminals, providing a robust solution for monitoring leakage currents in low-voltage electrical systems. The transformer is designed for use with ABB residual current monitors where sensitivity and intervention parameters can be configured through the connected monitoring device.
With a 60 mm internal diameter, the ABB TR2 is suitable for applications requiring larger conductor accommodation while maintaining accurate residual current measurement. Its compact construction and DIN rail system compatibility make it ideal for integration into electrical distribution boards and control panels.
Toroidal transformers such as the ABB TR2 detect leakage currents by measuring the imbalance of current flow through conductors passing through the transformer core. When connected to a suitable residual current monitoring relay, they provide continuous monitoring of electrical insulation conditions.
The ABB TR series is designed for engineers and installers requiring accurate measurement, compact dimensions and dependable operation in low-voltage distribution and industrial control systems.
