All control characteristics are based on a 4-pole asynchronous motor.

7.7 Fuses and Circuit Breakers

7.7.1 Recommendations

• American Wire Gauge. Maximum cable cross-section is the largest cable cross-section that can be attached to the terminals.
Always observe national and local regulations.
• Type gG pre-fuses must be used. To maintain UL/cUL, use pre-fuses of these types (see
• Measured using a 10 m (32.8 ft) shielded/armored motor cable with a rated load and rated frequency.
Fuses
