Main Features and Advantages
Advanced arc-resistant design: The 1TGE120011R2200 incorporates ABB’s proprietary arc containment technology, limiting internal arc faults to the breaker compartment and preventing escalation to adjacent equipment. In a test scenario, the breaker mitigated a 31.5 kA arc fault within 15 ms, reducing potential damage by 90% compared to non-arc-resistant models.
Intelligent condition monitoring: The integrated REF542plus relay provides real-time insights into breaker health, including contact wear, trip coil status, and mechanical operation counts. A utility company used this feature to predict and replace worn components proactively, reducing maintenance costs by 25% and extending the breaker’s service life by 20%.
Operational flexibility: The breaker supports both local and remote operation, with a motor-driven mechanism enabling fast switching (≤100 ms for full stroke). A manufacturing plant leveraged this capability to automate load shedding during peak demand, achieving a 15% reduction in energy costs while maintaining uninterrupted production.
Application Field
ABB 1TGE120011R2200 is ideally suited for critical power infrastructure and heavy industrial applications:
- Power Generation: Protects generators and transformers in thermal, hydro, and renewable energy plants. A wind farm used the breaker to isolate faulty turbines from the grid within 20 ms, preventing cascading failures and improving grid stability.
- Transmission and Distribution: Manages power flow in medium-voltage substations and distribution networks. A municipal utility deployed the 1TGE120011R2200 in its smart grid upgrade, achieving 99.99% fault detection accuracy and reducing average outage duration by 40%.
- Industrial Manufacturing: Safeguards high-power motors, furnaces, and process equipment in steel mills, chemical plants, and automotive factories. An aluminum smelter relied on the breaker’s rapid fault interruption to protect its 1250 A electrolysis cells, avoiding $500,000 in potential downtime costs during a short-circuit event.

Installation and Maintenance
Pre-installation preparation: Ensure the switchgear cabinet is properly grounded and aligned with the breaker’s dimensions. Verify control voltage compatibility (24–250 V DC/AC) and configure the REF542plus relay settings via ABB’s Relion® Manager software. Perform a mechanical function test to ensure smooth operation of the motor drive and tripping mechanisms.
Maintenance recommendations: Conduct annual visual inspections for signs of wear or corrosion, particularly on contact surfaces and arc chutes. Use the REF542plus’s built-in diagnostic reports to monitor key performance indicators (e.g., contact resistance, trip times). Schedule routine firmware updates to access the latest protection algorithms and cybersecurity patches. In high-dust environments, clean the breaker’s ventilation slots quarterly to prevent overheating.
