Danfoss recommends using the fuses/circuit
breakers listed below to protect service
personnel and property in case of component
break-down in the frequency converter. For
circuit breakers, Moeller types have been tested
and are recommended. Other types of circuit
breakers may be used provided they limit the
energy to a level equal to or lower than the
Moeller types.
