Catalog Description | Amp-Trap 2000 A4BQ fuses are 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 percent of rated current) accommodates harmless inrush currents with no nuisance opening. 600 Volts 800 amps A4BQ series. |

Special Features | Fastest operation under short circuit conditions: Let-thru currents are typically 20 percent lower, with a corresponding let-thru energy (clearing I2t) 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 let-thru current even at fault currents up to 300kA Recommended for Arc Flash energy reduction 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 replacement errors High-visibility orange label gives instant brand recognition Reduced inventory because A4BQ can replace all older types of Class L fuses now in-service Metal-embossed date and catalog number for traceability and lasting identification Fiberglass body provides dimensional stability in harsh industrial settings High-grade silica filler ensures fast arc quenching Optional mechanical TA indicator (100-6000A).
