Why Choose the ABB 1SDA105131R1 RC Sel x XT5 4-Pole Residual Current Release?
The ABB 1SDA105131R1 is a selective residual current release designed for compatible ABB SACE Tmax XT5 four-pole moulded case circuit breakers. Identified as RC Sel x XT5 4p, this dedicated protection accessory adds residual current monitoring and tripping functionality to suitable XT5 circuit-breaker installations.
As part of the ABB SACE Tmax XT residual current device range, the RC Sel provides selective earth-leakage protection for applications where coordination with other protective devices is important. Its adjustable residual current and time-delay characteristics allow the protection response to be configured for the requirements of the electrical distribution system.
The 1SDA105131R1 is designed for 4-pole XT5 circuit breakers and operates across a rated voltage range of 85–500 V AC. It provides an adjustable residual operating current range of 0.03–30 A and adjustable operating delay, making it suitable for industrial and commercial low-voltage distribution systems requiring selective residual current protection.

Selective Residual Current Protection for Tmax XT5
Residual current releases monitor leakage current to earth and initiate circuit-breaker tripping when the configured residual current protection threshold is exceeded. A selective device incorporates adjustable timing characteristics that can help coordinate upstream and downstream protection, reducing unnecessary interruption of unaffected sections of an electrical distribution system.
The ABB RC Sel x XT5 4p combines residual current monitoring with adjustable sensitivity and delay settings in a dedicated accessory for four-pole Tmax XT5 breakers. This makes it suitable for distribution systems where dependable earth-leakage protection and selective coordination are required alongside the primary overcurrent protection provided by the circuit breaker.
Typical Applications
- ABB SACE Tmax XT5 four-pole circuit breaker installations.
- Industrial low-voltage distribution systems.
- Commercial electrical distribution boards.
- Switchboards requiring selective residual current protection.
- Power distribution circuits requiring earth-leakage monitoring.
- Electrical installations requiring coordinated residual current protection.
