Product Overview

The HIES308461R0012 is a high-energy water-cooled power resistor engineered for ABB heavy-duty variable frequency drives. It dissipates regenerative braking energy generated during rapid motor deceleration, converting excess electrical energy into heat and removing it via circulating cooling water. Its liquid cooling design delivers far higher continuous power density than air-cooled alternatives, avoiding thermal overload in cyclic braking, hoist, crane and high-inertia process applications. Built with robust high-voltage insulation, this resistor maintains stable resistance under heavy pulse loads. It is widely stocked as a critical legacy spare for ACS800 and comparable high-power drive systems in mining, marine, steel and power plants.
