Short Description

Amp-Trap A4BY fuses have been the industry's favorite when it comes to protecting service entrance equipment, feeder circuits, and circuit breakers. The A4BY is a 100% rated device and may be applied at continuous currents up to its ampere rating. A 4-second minimum time delay at 500% rating allows the A4BY to pass normal current surges and to coordinate with ground fault relays.

Features

  • Unique dimensions prevent replacement by other fuse classes
  • Blade stamped catalog numbers for permanent identification
  • Glass melamine body and plated terminals provide superior reliability in harsh environments
  • Uniform characteristics in all ampere ratings
  • North American power fuses
