Overview

The ABB Braking Resistor (SKU: ABB-44544) is a precision-engineered component for industrial motor control systems, designed to safely dissipate excess energy during deceleration. With a resistance of 6.39 ohms and a continuous power rating of 21,955 watts, it handles high-energy braking cycles in demanding applications. The resistor is housed in a GCE30 enclosure, providing IP20-rated protection against dust and accidental contact. Measuring 28 inches wide by 16 inches deep by 10 inches high and weighing 58 pounds, this unit is built for heavy-duty use in manufacturing, automation, and process control systems. It is specifically compatible with ABB Low Voltage Drives, ensuring seamless integration with existing drive systems. The resistor prevents voltage spikes that can damage motors and drives, extending equipment lifespan while maintaining operational stability. Its robust construction and precise electrical ratings make it suitable for applications requiring frequent start-stop cycles or dynamic braking.

Frequently Asked Questions

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

Braking resistors dissipate regenerated power to prevent bus voltage from exceeding the drive's rated limit, increasing braking torque for faster, controlled braking.

What is the purpose of braking choppers (modules)?

Braking modules monitor the drive's DC bus and activate external braking resistors to manage regenerated power and prevent over-voltage trips.

What wire type should be used when connecting directly to resistors in Type ED enclosures?

If installing without optional terminal connections, always use 200ºC rated silicone or Teflon wire when attaching directly to resistors.

What is the function of the thermal switch in Type GCE and ED enclosures?

The normally closed thermal switch detects resistor temperature overloads and is used to alert or shut down the system if the temperature becomes too high.

What is the conduit knockout size for Type GCE enclosures?

The Type GCE enclosures have removable 1/2 inch conduit knockouts for routing standard 90ºC rated wire.

What is the purpose of the aluminum case in Type CR resistors?

The aluminum case is corrosion-resistant and helps dissipate heat from the resistor element, allowing for efficient cooling.

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.

What is the typical duty cycle for the listed braking resistors?

The duty cycles listed include 3sec on/27sec off, 10sec on/50sec off, 30sec on/180sec off, and 60sec on/180sec off.

What is the maximum continuous current rating for terminal connections in Type ED enclosures?

Type ED enclosures supply terminal connections up to 400 amps continuous.

What are the voltage ratings for ACS250 drives?

ACS250 drives are available for single-phase 100-120V and 200-240V applications, and three-phase 200-240V and 380-480V applications.
