The LDFJ Series fuses provide space-saving, high-speed performance and short-circuit protection for AC and DC drives. These fuses offer current-limiting features with low I2T for protection of power semiconductor devices and motor controllers. They have the lowest let-through energy of any branch circuit overcurrent protective device. These fuses are easily coordinated with existing and new variable speed drives and electric controllers.
