CLASS L POWER FUSES

PUT THE HIGHEST
CURRENT-LIMITATION . . .
AT YOUR SERVICE.
Amp-trap 2000® A4BQ fuses are 20% more current limiting than any other Class L fuse on the market.
When correctly coordinated, they bring a superior level of protection to service entrance equipment.
Downstream circuit components have maximum protection against short circuit let-thru current. A4BQ’s
built-in, 4-second time delay characteristic (at 500% of rated current) accommodates harmless inrush
currents with no nuisance opening.
Features / Benefits
Fastest operation under short circuit conditions: Let-thru currents are typically 20% lower with a
2
corresponding let-thru energy (clearing l t) up to 40% lower than the next fastest Class L fuse.
Time delay for high inrush loads such as motors and transformers, without nuisance opening.
300kA interrupting rating - self-certified, UL witnessed tests.
Most current limiting for lowest peak letthru current; even at fault currents up to 300kA.
Pure silver links ensure lowest let-thru current and longer fuse life.
Easy 2-to-1 selectivity for prevention of nuisance shutdowns and “blackouts:
Rejection-style design prevents replacements errors.
High-visibility orange label gives instant recognition.
Reduced inventory because A4BQ can replace all older types of Class L fuses now in service.
Metal-embossed date and ref number for traceability and lasting identification.
Fibreglass body provides dimensional stability in harsh industrial settings
High-grade silica filler ensures fast arc qenching.
