LA30QS Semiconductor Fuses
300 VAC ■ Very Fast-Acting ■ 35 – 4500 Amperes

   Littelfuse’s 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 at 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.
