The TR3 ring core transformer from ABB is a highly advanced transformer specifically designed for the precise measurement of leakage and fault currents to ground. With a diameter of 80 mm, this ring core transformer provides a reliable solution for applications that require accurate monitoring of electrical currents. The transformer is compatible with differential current relays such as RD2 or RD3, which are capable of detecting potential fault currents and, if necessary, disconnecting them using appropriate protective devices, such as circuit breakers. Manufactured in Italy, the TR3 ring core transformer reflects ABB's commitment to quality and innovation and is a valuable component in modern electrical systems.

• Compatible with differential current relays RD2 and RD3 for fault current measurement
• Enables disconnection through appropriate protective devices
• Manufactured in Italy to high quality standards.
