Reliable Overcurrent Protection for Critical Electrical Systems
The
ABB 1TGE120021R0010 is a high-performance low-voltage (LV) circuit breaker designed to protect electrical systems and equipment from overcurrent, short circuits, and overloads. As part of ABB’s Tmax® XT series—renowned for industrial durability and precision—the 1TGE120021R0010 delivers consistent protection in LV power distribution networks, ensuring safe and uninterrupted operation of machinery, lighting, and critical electrical loads.
Engineered for easy integration into panelboards, switchgear, and distribution cabinets, this circuit breaker combines robust construction with intuitive operation, making it ideal for industrial facilities, commercial buildings, and infrastructure projects where electrical safety and reliability are non-negotiable.
Equipped with a thermal-magnetic tripping unit:
- Thermal element: Protects against overloads by triggering a delayed trip when current exceeds safe levels (prevents unnecessary shutdowns from temporary surges).
- Magnetic element: Instantly trips during short circuits (≤ 100 ms response time), minimizing damage to cables, motors, and equipment.
50 kA breaking capacity at 415 V AC ensures the breaker safely interrupts high fault currents—critical for industrial environments with large motors or high-power loads.
Molded case construction with flame-retardant materials resists impact, chemical exposure, and temperature fluctuations, ensuring long-term reliability in harsh settings (e.g., factories, warehouses, construction sites).
- Panel-mounted design fits standard LV enclosures, with clear labeling for wiring terminals.
- Front-accessible handle and trip indicator simplify status checks (e.g., “ON/OFF/TRIPPED” visual cues).
- No special tools required for routine inspection, reducing maintenance time.
Compatible with both 1-phase and 3-phase LV networks, supporting diverse loads: motors, HVAC systems, lighting, and industrial machinery. The 100 A rated current makes it suitable for medium-sized electrical circuits.
Meets global standards (IEC, UL, CSA, VDE) for electrical safety, ensuring compliance with local regulations in North America, Europe, and Asia—ideal for multi-site or international projects.
Compact dimensions (85x180x105 mm) maximize panel space, allowing integration with other LV components (e.g., contactors, relays) in dense distribution systems.
The ABB 1TGE120021R0010 is widely used in:
- Industrial Facilities: Protection of LV circuits powering assembly lines, pumps, compressors, and manufacturing machinery (automotive, food processing, pharmaceuticals).
- Commercial Buildings: Distribution panel protection for lighting, HVAC, and office equipment in malls, hotels, hospitals, and data centers.
- Infrastructure: LV power distribution in airports, railways, water treatment plants, and renewable energy (solar/wind) auxiliary systems.
- Retail & Hospitality: Safeguarding electrical circuits in supermarkets, restaurants, and high-rise residential buildings.
- Construction Sites: Temporary power distribution for tools and equipment (with compatible weatherproof enclosures).
The 1TGE120021R0010 integrates seamlessly with:
- ABB LV panelboards (e.g., MNS® 3.0, Okken®) for complete distribution solutions.
- ABB contactors and soft starters (e.g., AF series) for motor control circuits.
- ABB thermal overload relays (e.g., TA series) for enhanced motor protection.
- Building Management Systems (BMS) via optional auxiliary contacts (for remote status monitoring).
- ABB Ability™ Electrical Distribution Control (EDC) platform (for centralized circuit monitoring and energy management).
Designed for user-friendly deployment:
- Mounting: Secure to panel using standard screws (compatible with IEC 62271-302 enclosure dimensions).
- Wiring: Connect line/load cables to labeled terminals (copper or aluminum conductors up to 50 mm²).
- Operation: Manual ON/OFF control via front handle; trip indicator resets with a simple push after fault clearance.
- Safety: Lockable handle option prevents unauthorized operation (complies with OSHA lockout/tagout standards).
