| Special Purpose Fuses LA15QS Semiconductor Fuses 150 VAC * Very Fast Acting * 1 - 6000 Amperes Littelfuse LA15QS series Semiconductor fuses were designed for the specific protection of diodes and other semiconductor devices rated 150VAC/DC. The LA15QS product line compact design is perfect for those applications that have limitations on available space. 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. Applications Protection of heavy duty devices such as electromechanical rectifiers.
