Fuse Class L 800A A4BY Series MPN:A4BY800
Mersen's A4BY Series Class L fuses provide reliable overcurrent protection for electrical feeders and service equipment in a current-limiting design. Their time-delay action prevents nuisance-blowing during motor or equipment startups, while their capacity to open under sustained loads helps protect against fire and equipment damage due to short circuits. With an 800A rating and a secure bolted mounting, these fuses are ideal for industrial, commercial, and residential applications where circuit protection is critical. Their absence of an indicator can be accommodated with a fuse block or cover, providing cost savings without sacrificing functionality. Trust Mersen's Class L fuses to protect your electrical system from the harshest conditions.
