1SDA105221R1 ABB SW Adaptive Protection XT2-XT4 Factory-Fitted Software Package

Why Choose the ABB SW Adaptive Protection XT2-XT4 1SDA105221R1 Software Package?

The ABB 1SDA105221R1 is an Adaptive Protection software package for compatible ABB SACE Tmax XT2 and XT4 circuit breakers equipped with supported Ekip Touch electronic trip units. It adds ABB's adaptive protection functionality, allowing two different sets of protection parameters to be configured for changing electrical network conditions.

Adaptive protection is particularly useful in installations that can operate both grid-connected and in island mode. Fault-current levels can change substantially when the installation is disconnected from the utility supply, so a single set of protection thresholds may not provide optimum selectivity in both operating conditions. ABB Adaptive Protection allows the active protection settings to change between Set A and Set B to suit the operating state of the system.

The 1SDA105221R1 is specified here as a factory-fit-only software option, allowing the functionality to be selected as part of the compatible circuit-breaker configuration during manufacture. For applicable Ekip Touch configurations, the Measuring package is required before the Adaptive Protection function can be added.

• Available for supported Ekip Touch configurations.
• Requires the compatible Measuring package when used with applicable Ekip Touch trip units.

Adaptive Protection for Changing Network Conditions

Electrical protection settings that are appropriate while an installation is connected to the utility network may not be optimum when the same system operates from local generation in island mode. Utility contribution can produce higher fault currents when grid connected, while available short-circuit current can fall significantly after separation from the grid. ABB Adaptive Protection addresses this challenge by providing two protection parameter sets that can be applied according to the operating condition.

With the 1SDA105221R1 package and a correctly configured compatible system, the Ekip protection platform can use Set A and Set B to accommodate these changing conditions. This makes the functionality particularly valuable in installations incorporating distributed generation, microgrids and other electrical systems where maintaining protection selectivity and continuity across different operating states is important.

Typical Applications

• ABB SACE Tmax XT2 and XT4 circuit-breaker installations.
• Microgrids capable of grid-connected and island operation.
• Electrical systems incorporating local generation.
• Industrial distribution systems with changing short-circuit conditions.
• Critical-power installations requiring coordinated protection across different operating states.
• Commercial and infrastructure systems using compatible Ekip Touch protection units.
