What it is and where it's used
The FR-ABR-15K is a high-duty brake resistor from Mitsubishi, part of the brake systems range under Motors & Motor Controls. It dissipates regenerative energy from a motor drive during deceleration, preventing DC bus overvoltage in VFD applications. Rated for high-duty cycles—typically found in applications with frequent or rapid braking, such as conveyors, elevators, or crane hoist drives—this resistor handles repeated thermal pulses better than standard-duty units.
