Note
The fuses are IEC rated (where the name plate value is the expected
current carrying rating) and not UL or CSA rated (where the name plate
value is nearly the current blowing rating). Use of UL or CSA rated fuses
will cause unnecessary blowing at high loads.
Appropriate replacement fuses include:
•
Bussmann GDC-T315 mA or equivalent for the 0.315 A fuse
•
Bussmann GDC-T630 mA or equivalent for the 0.63 A fuse
•
Bussmann GDC-T1.25 A or equivalent for the 1.25 A fuse
