ABB HIES308461R0002 Water-Cooled Braking Resistor

Product Description

The HIES308461R0002 is a high-power water-cooled braking resistor manufactured by ABB (Fischer Reinach), designed for ABB ACS800 / ACS880 high-power variable frequency drives. It consumes regenerative energy generated by the motor during deceleration, converts excess electric energy into heat and dissipates it via circulating cooling water. It is widely used in heavy-duty high-power drive cabinets for metallurgy, hoisting, mining and rolling mill applications.

FAQ

Q: What is the difference between HIES308461R0002 and HIES308461R0012?
A: The suffix number represents different resistance values and power ratings; 0002 and 0012 are different ohm specifications for different braking energy requirements.

Q: Why use water-cooled braking resistor instead of air-cooled?
A: Water cooling has much higher heat transfer capacity, suitable for high-power, frequent braking scenarios where air cooling resistors cannot meet heat dissipation requirements.

Q: Is this resistor discontinued?
A: This legacy water-cooled braking resistor series is end-of-life, supplied as surplus, refurbished and tested spare parts only.

Q: Does it need to work with a braking chopper?
A: Yes, it must cooperate with the inverter braking chopper unit to complete regenerative energy discharge.
