Overview

The ABB Braking Resistor (SKU: ABB-48431-334) is a high-power resistor designed for motor braking applications in industrial systems. With a resistance of 2.2 ohms and a power rating of 40,095 watts, it efficiently dissipates energy generated during motor deceleration, preventing voltage spikes that can damage variable frequency drives (VFDs) and other motor control components. The ED4 enclosure provides IP54-rated protection against dust and water ingress, ensuring reliable operation in harsh environments. This resistor is optimized for use in braking circuits where rapid motor stops are required, such as in cranes, elevators, and conveyor systems. Its compact dimensions (30 inches wide x 18 inches deep x 32 inches high) and 205-pound weight make it suitable for installations with space constraints. The resistor is manufactured in the US by ABB Low Voltage Drives, a leader in industrial motor control solutions. Key specifications include: - Resistance: 2.2 ohms - Power rating: 40,095 watts - Enclosure: ED4 (IP54-rated) - Dimensions: 30W x 18D x 32H inches - Weight: 205 lbs - UNSPSC Code: 39122004

Frequently Asked Questions

What is the purpose of a braking resistor with a variable frequency drive?

A braking resistor is required for applications needing faster deceleration or when motor speeds exceed synchronous speed, dissipating regenerated power to prevent bus voltage from exceeding drive limits.

What is the voltage range for ACS150 and ACS355 single-phase applications?

These drives are designed for single-phase 200-240V applications.

What is the voltage range for ACS150 and ACS355 three-phase applications?

These drives are designed for three-phase 200-240V and 380-480V applications.

What is the voltage range for ACS250 single-phase applications?

These drives are designed for single-phase 100-120V and 200-240V applications.

What is the voltage range for ACS250 three-phase UL Type 4X drives?

These drives are designed for three-phase 200-240V and 380-480V applications.

What is the voltage range for ACS250 three-phase drives (non-UL Type 4X)?

These drives are designed for three-phase 575-690V applications.

What is the voltage range for ACS550 three-phase applications?

These drives are designed for three-phase 200-240V and 380-480V applications.

How are Powerohm Type CR resistors constructed?

They feature a nickel-chromium wire helically wound inside a ceramic fixture, placed in a corrosion-resistant aluminum case with high-temperature wire leads and ceramic potting.

What is the purpose of braking resistors in variable speed drive systems?

Braking resistors dissipate regenerated power from the motor back into the drive, preventing the DC bus voltage from rising and causing an over-voltage trip.

What are the typical applications for braking resistors?

They are used in applications requiring faster deceleration rates or where motor speeds exceed synchronous speed due to overhauling load conditions.
