Mersen A4BQ Amp-Trap 2000 Time-Delay/Class L Fuse with Remote Blown Fuse Trigger Actuator, 600VAC/500VDC, 200kA AC/100kA DC, 6000 Ampere, 7-1/8" Diameter x 10-3/4" Length

Mersen Amp-Trap 2000 A4BQ fuses with remote blown fuse trigger actuator are 20 percent 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 without nuisance opening. 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 percent lower than the next fastest Class L fuse. Most current-limiting for lowest peak let-thru current; even at fault currents up to 300kA. 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-ser
