Product Description

• Estimated Lead Time : 6 - 8 weeks.

• Manufacturer : Danfoss

• Part Number : 131B0453

• Product Type : Brake Resistor (External Dynamic Braking Unit)

• Compatible VFD Series : Danfoss VLT (Used with various drive models, often including the FC 300 series, depending on the power rating).

• Function : Dissipates regenerative energy (power fed back from the motor) into heat during braking. This keeps the drive's DC bus voltage from exceeding safe limits and tripping the drive.

• Resistance Value : Typically specified as 40 Ohms (Exact value is critical and matched to the specific VFD model and frame size it protects).

• Power Rating : Designed for specific continuous or high-cycle braking duties, matched to the motor/drive size.

• Enclosure : Usually a robust IP20 or equivalent metallic enclosure, designed for wall mounting external to the drive cabinet.

• Key Feature : Essential for applications requiring fast stops, controlled deceleration, or handling high-inertia loads (like flywheels, cranes, or centrifuges).

• Product Net Weight : Approx. 2.5 Kg (2500 grams/5.5 lbs)
