Mersen AMP-TRAP® 2000 SmartSpot® A4BQ200 Current Limiting Low Voltage North American Time Delay Power Fuse, 200 A, 600 V AC, 200 kA Interrupt, L Class, Cylindrical Body
Amp-Trap 2000 A4BQ fuses 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 500percent of rated current) accommodates harmless inrush currents with no nuisance opening.

- 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 (when used with recommended fuse blocks)
- 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
