Specifications
8.2.1 Fuses
It is recommended to use fuses and/ or circuit breakers on the supply side as protection in case of component break-down
inside the drive (first fault).
NOTE
This is mandatory in order to ensure compliance with IEC 60364 for CE or NEC 2009 for UL.
WARNING
Personnel and property must be protected against the consequence of internal component break-down in the drive.
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 protected against short-circuit and overcurrent according to national/international regulations.
NOTE
The recommendations given do not cover branch circuit protection for UL.
Short-circuit protection:
GE recommends using the fuses/circuit breakers mentioned below to protect service personnel and property in case of
component break-down in the drive.
Overcurrent protection:
The drive provides overload protection to limit threats to human life, property damage and to avoid fire hazard due to
overheating of the cables in the installation. The drive is equipped with an internal overcurrent protection (F-43 Current
Limit) that can be used for upstream overload protection (UL applications excluded). Moreover, fuses or circuit breakers can
be used to provide the overcurrent protection in the installation. Overcurrent protection must always be provided in
accordance with national regulations.
WARNING
In case of malfunction, not following the recommendation may result in personnel risk and damage to the drive and other
equipment.
The following tables list the recommended rated current. Recommended fuses are of the type gG for small to medium
power sizes. For larger powers, aR fuses are recommended. Circuit breakers must be used provided they meet the national/
international regulations and they limit the energy into the drive to an equal or lower level than the compliant circuit
breakers.
If fuses/circuit breakers are chosen according to recommendations, possible damage to the drive will be limited to damage
mainly within the unit.
8.2.2 CE Compliance
Fuses or circuit breakers are mandatory to comply with IEC 60364. GE recommend using a selection of the following.
The fuses below are suitable for use on a circuit capable of delivering 100,000 Arms (symmetrical), 240 V, or 480 V, or 500 V,
or 600 V depending on the drive voltage rating. With the proper fusing, the drive short circuit current rating (SCCR) is
100,000 Arms.
