Why Choose the ABB RC Sel x XT3 3p F Residual Current Release?
The ABB RC Sel x XT3 3p F is a selective residual current release designed for ABB SACE Tmax XT3 moulded case circuit breakers. Identified by ABB order code 1SDA067128R1, it provides residual current protection for compatible fixed three-pole XT3 circuit breakers in low-voltage electrical distribution systems.
As part of the ABB SACE Tmax XT accessory range, this RC Sel unit is designed to detect residual currents and provide an appropriate trip function when an earth leakage condition exceeds the configured protection parameters. Its selective operating characteristic supports coordinated residual current protection within installations where continuity and discrimination between protective devices are important.
The 1SDA067128R1 is specifically designed for fixed 3-pole Tmax XT3 circuit breakers and operates across an 85–690 V AC voltage range. Manufactured for integration with the XT3 platform and compliant with IEC 60947-2, it provides a manufacturer-matched residual current protection solution for industrial and commercial low-voltage distribution applications.

Selective Residual Current Protection for Tmax XT3
Residual current releases monitor electrical installations for current imbalance associated with leakage to earth. When a residual current reaches the applicable protection threshold, the release works with the circuit breaker to disconnect the affected circuit, helping protect the electrical installation against earth leakage faults.
The ABB RC Sel 1SDA067128R1 provides selective residual current functionality for compatible fixed three-pole Tmax XT3 circuit breakers. Its dedicated XT3 design and broad 85–690 V AC operating range make it suitable for coordinated protection arrangements in professional low-voltage switchboards and distribution systems.
