Factory Recommended Branch Circuit Protection
WARNING! Fire Hazard. Install adequate branch circuit protection according to applicable local codes and this manual. Failure to comply
could result in fire and damage to the drive or injury to personnel. The device is suitable for use on a circuit capable of delivering not more
than 100,000 RMS symmetrical amperes, 240 Vac (200 V class) and 480 Vac (400 V class), when protected by branch circuit protection
devices specified in this manual.
Branch circuit protection shall be provided by any of the following: Non-time delay Class J, T, or CC fuses sized at 300% of the drive input
rating, or Time delay Class J, T, or CC fuses sized at 175% of the drive input rating, or MCCB sized at 200% maximum of the drive input
rating.
Yaskawa recommends installing one of the following types of branch circuit protection to maintain compliance with UL508C.
Semiconductor protective type fuses are preferred. Alternate branch circuit protection devices are also listed in
