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.
