Installing Input Fuses - YASKAWA A1000 Technical Manual

D.3 UL Standards
 Installing Input Fuses
NOTICE: If a fuse is blown or equipment for residual current monitoring/detection (RCM/RCD) is tripped, check the wiring and the
selection of the peripheral devices. Check the wiring and the selection of peripheral devices to identify the cause. Contact YASKAWA
before restarting the drive or the peripheral devices if the cause cannot be identified.

Factory Recommended Branch Circuit Protection
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
Table D.8 and Table D.9.

<1> Maximum MCCB Rating is 15 A, or 200% of drive input current rating, whichever is larger. MCCB voltage rating must be 600 VAC or greater.
<2> Maximum Time Delay fuse is 175% of drive input current rating. This covers any Class CC, J or T class fuse.
<3> Maximum Non-time Delay fuse is 300% of drive input current rating. This covers any CC, J or T class fuse.
<4> When using semiconductor fuses, Bussmann FWH is required for UL compliance.
<5> This covers Class L fuse.
