LA100P Semiconductor Fuses
1000 VAC
I
Very Fast-Acting
I
15 1000 Amperes
SPECIFICATIONS
Voltage Rating: AC: 1000 Volts
DC: 750 Volts
Interrupting Rating: 100,000 Amperes
Ampere Range: 15 1000 Amperes
Approvals: UL Recognized under the components
program.
Littelfuse's LA100P semiconductor protection fuses are rated
1000V, extending the range of protection for UPS systems,
AC and DC drives, reduced voltage motor starters and simi-
lar applications where lower I
2
t and superior reliability are
needed. With ratings from 15-1000 amperes, a wide range of
high voltage applications can be served.
FEATURES
I
Low I
2
t minimizes damage to protected components on
short circuit.
I
Controlled arc voltage reduces stress to circuit compo-
nents during fuse clearing.
APPLICATIONS
Protection of UPS systems, AC/DC drives, reduced voltage
motor starters and other 1000V or less semiconductor
devices.
