2 Short Circuit Protection Requirements for UL Listing

WARNING

peripheral devices. Wait for the time specified on the warning label at a minimum and make sure that all indicators are OFF. Then
check the wiring and peripheral device ratings to find the cause of the problem. If you do not know the cause of the problem, contact
Yaskawa before you energize the drive or peripheral devices. If you do not fix the problem before you operate the drive or peripheral
devices, it can cause serious injury or death.

Electrical Shock Hazard. After the input protective device trips, do not immediately energize the drive or operate

◆ UL Compliance

Install one of these types of short circuit protection devices in Table 2.1 to comply with UL 508C. Semiconductor
protective type fuses are recommended, but the table also shows alternative short circuit protection devices.

■ Molded Case Circuit Breaker (MCCB) Ratings

• Maximum MCCB rating is 200% of the Normal-Duty drive full load output amp (FLA) rating.

• When you use MCCBs you must mount the drive in a ventilated enclosure according to the minimum enclosure

volume specified in this document.

Note:

When you use MCCBs, Yaskawa recommends the current-limiting type.

■ Semiconductor Fuse Ratings

• When you use semiconductor fuses as UL listed drive protection, the drives and fuses must be in the same

enclosure.

• Where multiple semiconductor fuse ratings are listed for a single drive, Yaskawa recommends the larger fuse for

cyclical load applications that frequently approach 150% overload. Smaller semiconductor fuses (than what is
listed) of the same manufacturer and series are permitted; however, this can cause fuses to clear prematurely.

■ Non-Semiconductor Fuse Ratings

• Maximum CC, J, T, RK1 or RK5 fuse rating is 175% of the Normal-Duty drive full load output amp (FLA) rating.

• When you use class CC, J, or T fuses as UL listed drive protection, models 4371 and larger have the same

minimum enclosure volume requirements as MCCBs.

• When you use RK1 or RK5 fuses, you must mount the drive in a ventilated enclosure according to the minimum

enclosure volume specified in this document.
