Littelfuse LA100P225-4 Special purpose fus Datasheet

Special Purpose Fuses
LA100P Semiconductor Fuses
1000 VAC • Very Fast Acting • 15 – 1000 Amperes
Littelfuse LA100P semiconductor protection fuses are rated 1000V,
extending the range of protection for UPS systems, AC and DC drives,
reduced voltage motor starters and similar applications where lower I2t
and superior reliability are needed. With ratings from 15-1000 amperes,
a wide range of high voltage applications can be served.
Features
• Low I2t minimizes damage to protected components on short-circuit.
• Controlled arc voltage reduces stress to circuit components during
fuse clearing.
Applications
Protection of UPS systems, AC/DC drives, reduced voltage motor
starters and other 1000V or less semiconductor devices.
