1TGE120020R0614 Heavy-Duty Contactor

High-Capacity Contactor for Industrial Power Distribution

Technical Specifications

Main Features and Advantages

Robust Power Switching: The ABB 1TGE120020R0614 delivers reliable 150A switching capacity for demanding industrial applications. Its silver-tin oxide contacts provide superior arc resistance and welding protection, ensuring consistent performance even under frequent start/stop operations of heavy motors.

Energy-Efficient Operation: Featuring low-power coil technology (≤15W), this contactor reduces energy consumption by up to 80% compared to conventional designs. The optimized magnetic circuit ensures positive contact closure while minimizing heat generation, extending operational life in high-cycling applications.

Modular Design Flexibility: Compatible with ABB’s comprehensive range of accessories including auxiliary contacts, mechanical interlocks, and surge suppressors. The ABB 1TGE120020R0614 supports vertical or horizontal mounting configurations, providing installation flexibility in space-constrained control panels.

Enhanced Safety Features: Integrated arc chambers direct and extinguish switching arcs safely, while the positive-break mechanism ensures contact separation even under welded conditions. The transparent cover allows visual inspection of contact status without disassembly, enhancing maintenance safety.

Industrial Durability: Designed for harsh environments, the contactor withstands vibration levels up to 5G and operates reliably in temperatures from -40°C to +60°C. Corrosion-resistant components ensure long-term performance in humid or chemically aggressive atmospheres common in industrial facilities.
