3.2 Fuse types:
Drive input fuses are required to disconnect the drive from power in the event of a component failure in
the drive’s power circuitry. The drive’s electronic protection circuitry is designed to clear drive output
short circuits and ground faults without blowing the drive input fuses. Table below shows the
recommended input fuse ratings for CVP inverter. For effective protection use fuses with current-limit
function, non delay type, also consider the applicable national and international regulations for short
circuit and over current protection.
For UL type approval consider the following fuse types RK5, CC or T.
For non UL type approval consider gG and aR type fuses.
gG:- (Overload and Short circuit protection)
aR ultra rapid (Short circuit protection only), suitable for protection of Power semiconductors.
TECO Molded case circuit breakers can be used in Place of the input fuse, consider the necessity
of back up fuse to provide correct protection according to the applicable national and
international regulations. Consult with your fuse suppliers if in doubt.
