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.

Ferraz Shawmut AMP-TRAP 2000® SmartSpot® Power Fuse, Low Voltage North American Style Time Delay, Series: A4BQ, Rejection, 1500 A, 600 VAC/500 VDC, 100/200 kA Interrupt, Class: L, Blade Terminal, Bolt-On Mount, Cylindrical Body, GMG, 3 in Dia x 10-3/4 in L Body Size

• Fastest operation under short circuit conditions - let-thru currents are typically 20% 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
• 300 kA interrupting rating, self certified (UL witnessed)
• Most current limiting for lowest peak let-thru current; even at fault currents up to 300 kA
• 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 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
• 200 kA at 600 VAC, 100 kA at 500 VDC interrupt rating
