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 s time delay characteristic (at 500% of rated current) accommodates harmless inrush currents with no nuisance opening.

Ferraz Shawmut Amp-Trap® 2000 SmartSpot® Power Fuse, Current Limiting Low Voltage North American Time Delay, Series: A4BQ, Non-Indicating, Rejection, 1000 A, 600 VAC, 200 kA Interrupt, Class: L, 4 s at 500% Response, Blade Terminal, Bolt-On Mounting, Cylindrical Body, Dual Element, Fiberglass, 2-1/2 in Dia x 10-3/4 in L Body

• Fastest operation under short circuit conditions let through currents are typically 20% lower, with a corresponding let through 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
• Rejection style design prevents replacement errors
• Most current limiting for lowest peak let through current, even at fault currents up to 300 kA
• Pure silver links ensure lowest let through current and longer fuse life
• Easy 2 to 1 selectivity for prevention of nuisance shutdowns and "blackouts"
• 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
• Silver plated copper contact
