Why Choose the ABB E1/6 Toroid Transformer for PR122/PR123?
The ABB E1/6 Toroid Transformer for PR122/PR123, order code 1SDA059145R1, is a dedicated toroidal current transformer accessory for ABB SACE Emax protection systems. It is intended for use with compatible PR122 and PR123 electronic trip units on E1–E6 frame applications where an external toroidal sensor is required for neutral or earth-fault measurement functions.
This accessory forms part of the ABB New Emax product family and is designed to provide the sensing input required by compatible protection electronics. The toroidal form allows a conductor or cable arrangement to pass through the transformer aperture so that current can be monitored without introducing a series connection into the main power path.
Used with compatible Emax circuit breakers and PR122/PR123 trip units, the 1SDA059145R1 supports protection and monitoring arrangements that rely on residual or neutral current measurement. Its dedicated ABB design helps ensure correct integration with the intended SACE Emax protection architecture.
