NEW ORDERING INFORMATION LA 15 QS 400 -4 TI Littelfuse Voltage (150) Style Ampere Rating Littelfuse’s LA15QS series Semiconductor fuses were designed for the specific protection of diodes and other semiconductor devices rated 150VAC/DC. The LA15QS product lines compact design is perfect for those applications that have limitations on available space. Mounting Type Ferrule Ferrule, midget dim. Blades/Bolt-in Hockey Puck, bolt-in 1 2 4 128 FEATURES I I I I 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. Integral Blown-Fuse Indicator Trigger Indicator Trigger Actuator TI IL Note: Mounting types and integral blown fuse indicators are optional for specified ratings. APPLICATIONS Protection of heavy duty devices such as electromechanical rectifiers.
