Special Purpose Fuses
LA50QS Semiconductor Fuses
500 VAC  •  Very Fast Acting  •  35 – 1200 Amperes
In response to new equipment requirements, Littelfuse LA50QS
series fuses were developed to improve the overall performance
of semiconductor fuses. The LA50QS provides the best protection
features including lower I²t, longer life when subjected to cyclic loading
and lower watts loss. LA50QS is today’s choice for the protection of
dynamic solid state equipment.
Features
• Lowest I²t for greatest protection of semiconductor circuits.
• Low watts loss for cooler operation.
• Superior cycling ability gives an equipment design advantage.
• State-of-the-art protection for 500 volt equipment.
• Ultra compact sizes allow down-sizing of existing equipment.
Applications
Protection of 500 volts or less solid state equipment such as motor
drives, UPS, inverters, etc.
