Why Choose the ABB 1SDA105211R1 Voltage Protection Software Package?
The ABB 1SDA105211R1, designated SW Voltages Protection, is a voltage protection software package for ABB SACE Tmax XT2 and XT4 circuit breakers equipped with compatible Ekip Touch electronic trip units. It expands the protection capabilities of the trip unit by enabling dedicated under-voltage, over-voltage, phase-sequence and voltage-unbalance protection functions.
The package enables six voltage protection functions: UV (ANSI 27), OV (ANSI 59), UV2 (ANSI 27), OV2 (ANSI 59), PS (ANSI 47) and VU (ANSI 47). These functions provide primary and secondary under-voltage and over-voltage thresholds together with phase-sequence and voltage-unbalance protection, allowing compatible Tmax XT circuit breakers to respond to a wider range of abnormal voltage conditions.
ABB identifies order code 1SDA105211R1 specifically for XT2-XT4 voltage protection. The functionality requires the Measurement Package to be enabled on the circuit breaker. When specified as a factory-fitted option, the digital functionality is activated as part of the configured circuit breaker, providing an integrated protection solution without requiring a separate physical protection accessory.
Key Advantages
- Genuine ABB voltage protection software package for SACE Tmax XT circuit breakers.
- Designed specifically for compatible XT2 and XT4 Ekip Touch applications.
- Adds both under-voltage and over-voltage protection functions.
- Provides primary and secondary voltage protection thresholds for enhanced system supervision.
- Adds phase-sequence and voltage-unbalance protection to compatible trip units.
- Software-based functionality integrates directly with the ABB Ekip digital protection architecture.
Key Features
- UV (ANSI 27): Under-voltage protection.
- OV (ANSI 59): Over-voltage protection.
- UV2 (ANSI 27): Second under-voltage protection threshold.
- OV2 (ANSI 59): Second over-voltage protection threshold.
- PS (ANSI 47): Phase-sequence protection.
- VU (ANSI 47): Voltage-unbalance protection.
- Designed for compatible ABB SACE Tmax XT2 and XT4 circuit breakers.
- Requires the compatible ABB Measurement Package functionality to be enabled.
Enhanced Voltage Protection for Digital Power Distribution
Voltage abnormalities can affect the reliability and operation of electrical equipment even when load current remains within normal limits. Under-voltage can cause motors and other equipment to operate incorrectly, while excessive voltage can place additional electrical stress on connected loads. Phase-sequence errors and voltage imbalance can also create problems for three-phase equipment, particularly rotating machinery.
The ABB 1SDA105211R1 package extends compatible Ekip Touch protection by adding dedicated voltage-based functions directly within the digital trip unit architecture. With two under-voltage and two over-voltage thresholds plus phase-sequence and voltage-unbalance protection, the package provides a comprehensive set of functions for monitoring and responding to abnormal supply voltage conditions.
Typical Applications
- ABB SACE Tmax XT2 and XT4 circuit breaker installations.
- Industrial low-voltage power distribution systems.
- Electrical systems requiring under-voltage and over-voltage protection.
- Three-phase systems requiring phase-sequence supervision.
- Installations requiring voltage-unbalance protection.
- Digitally configured switchboards using compatible ABB Ekip Touch trip units.
