Danfoss 135X0731 FC-302N450T5E21H2BGC7XXSXXXXAXBXCXXXXDX 450kW IP21 Brake VFD

Danfoss 135X0731, type FC-302N450T5E21H2BGC7XXSXXXXAXBXCXXXXDX, is an FC 302 frequency converter in the 450 kW class. This model retains IP21 protection and a brake chopper while selecting mains-option code 7. It is useful for comparing offers when the machine specification already identifies that exact factory combination.

The drive controls motor speed to meet the process demand. Selection must account for motor current, operating voltage, acceleration, stopping and overload duty. A shared power rating does not make two configurations directly interchangeable.

Key Features and Application Focus

• IP21 enclosure designation
• factory brake chopper

No A-slot option. IP21 braking and mains options is the main quotation focus. Assess use with the machine designer before specifying the drive for a particular load.

Supply and Quotation Information

Request a current quotation for 135X0731 with the complete type code, quantity and delivery destination. Pricing varies with the confirmed order scope. Estimated lead time is approximately 3 months, subject to confirmation at order placement. Ask the offer to state its validity, lead-time starting point and included accessories.

Compatibility and Selection Note

For an existing installation, send the original nameplate and parameter backup. Compare the supply, motor current, overload duty, enclosure, mains equipment, braking circuit and communication option. Any alternative needs a documented configuration review and commissioning plan. Matching 450 kW alone is insufficient.

Buying and Replacement FAQ

Q1. How do I request a price for 135X0731?

Send product code 135X0731, the full type code, quantity, destination and required date. Include the motor nameplate and application duty so the offer can be checked against the actual requirement.

Q2. What distinguishes this from 135X0730?

Both are IP21 braking variants, but their mains-option codes differ. Request a written comparison of the incoming-power equipment rather than accepting them under a single shortened model.

Q3. What must I confirm about mains-option 7?

Keep code 7 on the request and ask for the exact factory mains-equipment description. Confirm what is inside the drive package and what must be supplied externally before approving the price.

Q4. What should I send for the communication review?

Retain AX on the quotation request. This configuration has no factory A-slot option. If a network connection is needed, specify the protocol and obtain a revised configuration review.

Q5. When does the three-month lead time start?

Ask the quotation to define the starting event, such as order acceptance or payment confirmation. The estimated three months must also identify whether it covers dispatch or arrival. Confirm freight time separately.

Q6. Can another 450 kW drive replace this model?

Only after comparing the complete electrical, mechanical and control configuration. Check the original duty rating and motor current. Ask the offer to list every deviation and the required commissioning work before approving an alternative.
