GA500 Branch Circuit Protection

Use branch circuit protection to protect against short circuits and to maintain compliance with UL61800-5-1. Yaskawa
recommends connecting semiconductor protection fuses on the input side for branch circuit protection.
• 240 V model fuse selection:
Use the fuses specified in this document or in the drive product instructions to prepare the drive for use on a circuit that
supplies not more than 31,000 Amps RMS and not more than 240 Vac when there is a short circuit in the power supply.
• 480 V model fuse selection:
Use the fuses specified in this document or in the drive product instructions to prepare the drive for use on a circuit that
supplies not more than 31,000 Amps RMS and not more than 480 Vac when there is a short circuit in the power supply.
The built-in short circuit protection of the drive does not provide branch circuit protection. The user must provide branch
circuit protection as specified by the National Electric Code (NEC), the Canadian Electric Code, Part I (CEC), and local
codes.
