This TMC-18 Three-Phase AC Motor Contactor is a robust industrial-grade electrical component designed for demanding motor control applications. Built to handle currents up to 18A and operating voltages between 380V to 690V, this contactor excels in both 50Hz and 60Hz power systems. The versatile device is perfect for long-distance circuit breaking and frequent motor starting operations in industrial settings. Its reliable performance is maintained across challenging environments, functioning effectively in temperatures from -5° to +40°F, and at altitudes up to 6,562 feet. The black contactor features exceptional modularity - it can be integrated with auxiliary contact blocks, timer delays, and mechanical interlocking devices to create sophisticated control systems like star-delta starters. When combined with a thermal relay, it forms a complete electromagnetic starter solution. The unit is designed for stable mounting in locations with minimal vibration, making it ideal for industrial control panels and motor control centers. Its robust construction ensures consistent performance in industrial environments while maintaining reliable switching operations for motor control applications.
