10.8 Fuses, Circuit Breakers, and Switches

Fuses and circuit breakers ensure that possible damage to the drive is limited to inside the unit. Danfoss recommends fuses on the
supply side as protection. For further information, see Application Note Fuses and Circuit Breakers.
Use of fuses on the supply side is mandatory for IEC 60364 (CE) and NEC 2009 (UL) compliant installations.
