Overview

This ABB Low Voltage Drives Braking Resistor, SKU P14494-78, is designed to dissipate excess energy generated by motor applications, particularly during deceleration or regenerative braking. Featuring a robust 2 OHM resistance and a substantial 9800 WATTS power rating, this resistor is built for demanding industrial environments. It is housed within a GCE15 enclosure, providing protection and facilitating installation. The unit measures 26.5 inches in width, 16 inches in depth, and 5 inches in height, with a weight of 52 pounds. Its specifications make it suitable for applications requiring effective energy dissipation to prevent overvoltage conditions in variable frequency drives (VFDs) and other motor control systems. By absorbing and dissipating this energy as heat, the braking resistor ensures the safe and reliable operation of your motor control equipment, extending its lifespan and preventing potential damage. The GCE15 enclosure offers a practical form factor for integration into existing control panels or systems. This component is essential for applications where frequent braking or rapid deceleration is a requirement, such as in material handling, elevators, and process machinery. Ensure proper ventilation when installing to manage heat dissipation effectively. Consult your VFD's manual for specific compatibility and connection guidelines. UNSPSC Code: 39122004.

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.
