Fuse Class L 400A A4BQ Series MPN:A4BQ400
Fuse Class L 400A A4BQ Series
Time-delay, nonindicating UL Class L fuses tolerate temporary inrush currents without opening, which prevents nuisance-blowing from motor and equipment startups. Also called slow-blow Class L fuses, they open to disconnect an electrical circuit when exposed to sustained loads and short circuits. They have no indicator for identifying a blown fuse, so they're sometimes used with an indicating fuse block or cover.
UL Class L fuses protect electrical feeders and service equipment from overcurrent. These 600VAC fuses are not interchangeable with any other UL fuse class. They are current-limiting to prevent electrical damage by disconnecting circuits before they're exposed to the full magnitude and duration of an overcurrent. Class L fuses bolt onto their mountings for a secure hold that resists loosening from vibration and helps ensure proper seating to maintain contact with the circuit.
