8.1.2 UL/cUL Approved Pre-fuses

1. American Wire Gauge. Max. cable cross section is
the largest cable cross section that can be
attached to the terminals. Always observe
national and local regulations.
2. Type gG pre-fuses must be used. To maintain UL/
cUL, use pre-fuses of these types (see Table 8.2).
3. Measured using a 10 m screened/armoured
motor cable with a rated load and rated
frequency.
Recommended maximum pre-fuse size 25 A
