Fuses

 Branch circuit protection:

 In order to protect the installation against electrical and fire hazard, all branch circuits in an installation, switch gear, machines etc., must be short-circuited and

 overcurrent protected according to national/international regulations.

 Short circuit protection:

 GE Drive is suitable for a circuit capable of supplying a maximum of 100,000 Arms (symmetrical), 480 V maximum.

 Overcurrent protection:

 Provide overload protection to avoid overheating of the cables in the installation. Overcurrent protection must always be carried out according to national

 regulations.

 Non UL compliance:

 If UL/cUL is not to be complied with, GE recommends using the fuses mentioned in the below table, which will ensure compliance with EN50178/IEC61800-5-1:
