GE Industrial Solutions AF-600 FP Fan & Pump Drive (230V to 60HP, 460_575V to 125HP) - Manual (Page 74)

10.3 Fuse Tables
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 component break-down internally 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 over-current 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.
Over current 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 over current 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 over current
protection in the installation. Over current protection must
always be carried out according to national regulations.
10.3.1 Recommendations
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 according to recommendations are
chosen, possible damages on the drive will mainly be
limited to damages inside the unit.
