Overview

The ABB-44536 braking resistor (manufactured by ABB - Low Voltage Drives) is a 22-ohm, 3703-watt resistor designed for precise motor braking in industrial applications. This resistor dissipates regenerative energy from motors during deceleration, preventing voltage spikes that can damage drives and other components. The GCE9 enclosure provides IP20-rated protection against dust and moisture, ensuring reliable operation in harsh environments. With compact dimensions of 26.5 inches wide by 10 inches deep by 5 inches high and weighing just 23 pounds, the resistor is engineered for easy installation in control panels or machinery. It is ideal for use in manufacturing automation, conveyor systems, and heavy machinery where controlled braking is critical. The resistor’s 22-ohm resistance and 3703-watt power rating make it suitable for medium-duty braking applications, offering a balance of performance and durability. Compatible with ABB drives and other industrial motor control systems, this resistor enhances system safety and longevity by managing excess energy during braking cycles.

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.
