LA100P ALTERNATE DIMENSION SEMICONDUCTOR FUSES
1000 VAC • Very Fast-Acting • 15-1000 A
Description
Littelfuse LA100P semiconductor protection fuses are rated
1000 V, extending the range of protection for UPS systems,
AC and DC drives, reduced voltage motor starters and
similar 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/Benefits
• Low I
2
t minimizes damage to protected components on
short-circuit.
• Controlled arc voltage reduces stress to circuit
components during fuse clearing.
Specifications
Voltage Rating AC: 1000 V
DC: 750 V
