Special Purpose Fuses
LA30QS Semiconductor Fuses
300 VAC  •  Very Fast Acting  •  35 – 4500 Amperes
Littelfuse LA30QS series Semiconductor protection fuses are intended
for the protection of Power Semiconductors such as diodes, phase
control SCR’s and other power semiconductor devices. The LA30QS is
recommended for new applications providing solutions for your critical
protection needs for 300V and less semiconductors.
Features
• Low I²t minimizes damage to protected components on short-circuit.
• Controlled arc voltage reduces stress to circuit components during
fuse clearing.
• Choice of mounting types provides options for unique termination
requirements.
• Indicator options allow identification of blown fuses.
• Superior DC capabilities.
Applications
Protection of 300 volt heavy duty rectifiers and similar heavy duty
power supplies.
