Core advantages and technical highlights
High interrupting capacity: ABB 1TGE120011R1001 delivers exceptional breaking capacities—70 kA ultimate (Icu) and 50 kA service (Ics) at 415 V AC—enabling it to safely interrupt high fault currents without sustaining damage. This robust performance ensures reliable protection even in industrial environments with high inrush currents from motors, transformers, and other heavy loads. The breaker’s ability to withstand 50 kA for 1 second (Icw) provides valuable time for upstream protection devices to coordinate tripping sequences.
Precise protection customization: Equipped with an adjustable thermal-magnetic trip unit, ABB 1TGE120011R1001 allows fine-tuning of overcurrent protection settings. The thermal element protects against overloads with adjustable time delays, while the magnetic element provides instantaneous tripping for short-circuit faults with adjustable current thresholds. This flexibility ensures optimal coordination with other protective devices in the system, minimizing nuisance tripping while ensuring rapid response to genuine faults.
Durable and reliable construction: Built to withstand harsh industrial conditions, ABB 1TGE120011R1001 features a rugged molded case that provides mechanical strength and electrical insulation. Its operating mechanism ensures consistent performance across 10,000 manual operations and 100,000 electrical operations, delivering long service life with minimal maintenance. The breaker maintains reliable operation across a wide temperature range (-5°C to +70°C), making it suitable for challenging environments from cold storage facilities to high-temperature industrial zones.
Safety and compliance: ABB 1TGE120011R1001 meets rigorous international safety standards including IEC 60947-2 and UL 489, ensuring compliance with global electrical codes and regulations. Its IP20 protection rating (with IP40 option) prevents accidental contact with live parts, enhancing personnel safety during operation and maintenance. The breaker incorporates features like a visible contact position indicator and lockable handle, providing clear operational status and enabling safe isolation during maintenance procedures.
Typical application scenarios
In manufacturing facilities, ABB 1TGE120011R1001 protects low-voltage feeder circuits supplying production machinery, conveyor systems, and control panels. Installed in main distribution boards and motor control centers, the MCCB safeguards against overloads and short circuits that could damage expensive equipment or disrupt production. When integrated with REF615 HCFKAEADABCZDAA11E relays in medium-voltage systems, it forms a coordinated protection scheme where the MCCB handles low-voltage faults while the REF615 manages upstream medium-voltage protection, ensuring selective tripping that isolates faults with minimal system disruption.
Commercial and industrial building electrical systems utilize ABB 1TGE120011R1001 in distribution panels to protect lighting, HVAC, and power circuits. The breaker’s adjustable trip settings allow customization for different load types—providing proper protection for motor-driven HVAC equipment while preventing nuisance tripping from inrush currents. In smart building installations, the MCCB can be equipped with auxiliary contacts to communicate status information to building management systems, enabling remote monitoring of electrical system health and fault conditions.
Renewable energy installations, such as solar PV systems and small wind turbines, deploy ABB 1TGE120011R1001 in inverter protection circuits and low-voltage distribution. The breaker protects sensitive inverter equipment from overcurrent conditions while providing a means to safely isolate circuits during maintenance. Its ability to handle high fault currents ensures protection against faults in the DC-to-AC conversion equipment, while its wide temperature tolerance allows reliable operation in outdoor installations exposed to varying weather conditions.

Integration with protection systems
ABB 1TGE120011R1001 works seamlessly with advanced protection relays like REF615 HCFKAEADABCZDAA11E to create comprehensive electrical protection systems:
Coordination with medium-voltage protection: The MCCB’s adjustable trip settings enable precise coordination with the REF615 relay, ensuring that low-voltage faults are cleared by the 1TGE120011R1001 while the REF615 handles medium-voltage faults, preventing unnecessary upstream tripping and minimizing downtime.
Data integration: When equipped with auxiliary contacts or communication modules, the MCCB can send status information (open/closed position, trip events) to the REF615 or associated SCADA systems, providing visibility into low-voltage system conditions at the medium-voltage protection level.
Arc flash mitigation: In systems protected by REF615’s arc flash detection, the 1TGE120011R1001 acts as the final protective device that interrupts current during an arc flash event, working in conjunction with the relay’s rapid detection to minimize arc flash energy and reduce damage.
System isolation: The MCCB’s lockable handle provides a means to safely isolate low-voltage circuits during maintenance, complementing the REF615’s ability to isolate medium-voltage sections, ensuring comprehensive safety during system servicing.

Installation, commissioning and maintenance instructions
Installation preparation: Before installing ABB 1TGE120011R1001, verify the application’s current requirements match the breaker’s 100 A rating and that the system voltage does not exceed 690 V AC. Ensure the mounting location provides adequate ventilation and remains within the -5°C to +70°C operating temperature range. Select appropriate copper or aluminum conductors sized for 100 A continuous current, following local electrical codes for conductor termination torque specifications. Mount the breaker in a vertical position using panel mount or DIN rail (with adapter) methods, ensuring secure attachment to prevent vibration-related issues.
Commissioning steps: After installation, verify all electrical connections are tight and properly phased. Set the thermal trip unit’s overload current setting (Ir) to match the circuit’s maximum load current, typically 80-100% of the breaker’s rated current. Adjust the magnetic trip setting (Im) based on the maximum expected short-circuit current, typically 5-10 times the rated current depending on application. Perform manual operation tests to ensure the breaker opens and closes smoothly, verifying the position indicator shows correct status. Test the trip functionality using appropriate test equipment to confirm proper operation of both thermal and magnetic elements.
Maintenance suggestions: Perform annual visual inspections of ABB 1TGE120011R1001 to check for signs of overheating, corrosion, or physical damage. Verify the handle operates smoothly and the position indicator shows correct status. Clean dust and debris from the breaker and surrounding area using compressed air (maximum 5 bar). Test the breaker’s trip functionality every 3-5 years using secondary injection testing or by simulating overload conditions. Never use the breaker to interrupt fault currents as a test method. When integrating with protection systems like REF615 HCFKAEADABCZDAA11E, test the coordination between devices during scheduled maintenance to ensure selective tripping remains effective.
