LA100P Semiconductor Fuses
1000 VAC • Very Fast Acting • 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 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.
Ordering Information
Note: Mounting types and integral blown fuse indicators are optional for
specified ratings.
