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.

  • Very Low I2t for improved protection of equipment
  • Superior cycling ability for long, reliable life on high cyclic loading
  • Low watts loss for cooler operation
  • 700V AC/DC rating gives greater design versatility
  • Ultra compact sizes allow down-sizing of existing equipment
