CEFCO LR14742 Fuse

The CEFCO LR14742 fuse is a high-current, low-voltage protective device rated for 450 A and up to 600 V, designed to shield electrical circuits from overloads and short circuits in distribution equipment and industrial power systems. As a member of CEFCO’s line of low-voltage fuses, LR14742 provides robust interrupting protection for large-current circuits and is suitable for use in applications where reliable overcurrent protection is required. With a 450 A current rating and 600 V maximum operating voltage, this fuse is intended for medium- to high-load circuits within electrical distribution infrastructure. When installed in compliance with applicable electrical codes and the manufacturer’s guidelines, the LR14742 helps prevent conductor damage and equipment failure by quickly disconnecting the circuit under fault conditions, maintaining system safety and integrity.
