Frequently Asked Questions
What makes A4BQ fuses superior to other Class L fuses?
A4BQ fuses are 20% more current limiting and offer lower let-thru energy, providing superior protection for service entrance equipment.
What is the time-delay characteristic of A4BQ fuses?
A4BQ fuses have a built-in 4-second time-delay at 500% of rated current to accommodate inrush currents without nuisance opening.
What is the interrupting rating for A4BQ fuses?
A4BQ fuses have a 300kA interrupting rating, which is self-certified and UL witnessed for 600VAC.
What are the voltage and amperage ratings for A4BQ fuses?
They are rated for 600VAC and 500VDC. Amperage ratings range from 100 to 6000A for AC and 100 to 3000A for DC.
What does the '-TA' suffix indicate on A4BQ catalog numbers?
The '-TA' suffix indicates the optional mechanical trigger actuator (remote blown fuse indicator) is included.
What applications are A4BQ fuses recommended for?
A4BQ fuses are recommended for mains, feeders, large motors, lighting, heating, general loads, circuit breaker back-up, and DC applications like UPS links.
What standards are A4BQ fuses listed or certified to?
They are UL listed to Standard 248-10 and CSA certified to Standard C22.2 No. 248.10. DC ratings are listed to UL Standard 248.
Can a lower ampere rated Class L fuse replace a higher one?
Yes, a Class L fuse of any lower ampere rating can be substituted for a given Class L fuse due to their dimensioning.
What materials are used in A4BQ fuse links and bodies?
Pure silver links are used for low let-thru current and long life, while the fiberglass body provides dimensional stability.
What is the purpose of the rejection-style design?
The rejection-style design prevents replacement errors, ensuring the correct fuse type is used.
