Frequently Asked Questions

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

Braking resistors are 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 role of a braking chopper (module)?

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

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 encapsulated in ceramic potting material.

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

The normally closed thermal switch detects resistor temperature overloads, providing a safety mechanism to monitor and prevent overheating.

When should 200ºC rated wire be used with Type ED enclosures?

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