Reliance Electric B77C8400R Three-Phase Motor

Reliance Electric B77C8400R is a three-phase induction motor rated at 1/2 horsepower and running at 1140 RPM, designed for 200–240 V operation. The unit is built to frame FJ143TC and carries the official Reliance Electric model designation B77C8400R. As a 3-phase motor, it is intended for connection to a standard three-phase power supply, making it suitable for small industrial drives where compact size and reliable performance are important. Key specifications include the 0.5 HP rating, the 1140 RPM speed, the 200–240 V input range, and the 3-phase electrical configuration, all tied to the FJ143TC frame geometry that defines its mounting footprint. This combination of attributes—brand, model, horsepower, speed, voltage, phase, and frame—distinguishes the B77C8400R in catalogs and used-motor listings, helping buyers verify compatibility with existing equipment or retrofit projects that require a motor of this exact specification. These details—HP, RPM, voltage, phase, and frame—provide a precise, single-model reference for procurement and retrofit planning.
