Why Choose the ABB TR160 Toroidal Transformer?
The ABB TR160 is a closed-core toroidal transformer designed for residual current and earth leakage monitoring in low-voltage electrical installations. As part of the ABB TR toroidal transformer range, it works with compatible ABB residual current relays to detect leakage currents and support reliable earth fault protection in industrial and commercial distribution systems.
The TR160 provides a generous 160 mm internal diameter, allowing multiple conductors or larger cable assemblies to pass through the transformer aperture. Its closed-core construction provides a permanent sensing arrangement and is suitable for installations where conductors can be routed through the transformer during assembly or installation.
Designed for use with compatible ABB RD and ELR residual current relays, the TR160 has a 500/1 transformation ratio, IP20 protection and a maximum insulating voltage of 1000 V AC. Its robust design supports reliable residual current measurement in switchboards, distribution panels and industrial electrical protection systems.

Reliable Residual Current Detection
Toroidal transformers are used with residual current monitoring relays to detect an imbalance between currents flowing through the conductors of an electrical circuit. The active conductors pass through the transformer aperture, allowing the transformer to sense the residual current associated with leakage to earth and provide the corresponding measurement signal to the connected relay.
The ABB TR160 is particularly suited to applications requiring a larger conductor aperture. When combined with a compatible ABB residual current relay, it forms part of a configurable earth leakage monitoring and protection system for low-voltage electrical distribution equipment.
Typical Applications
- Residual current and earth leakage monitoring systems.
- Industrial switchboards and electrical distribution panels.
- Commercial low-voltage distribution systems.
- Industrial machinery and control panels.
- Large cable and multi-conductor installations.
- Electrical protection systems using ABB ELR residual current relays.
