Description

400A 600V TD L

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 100percent rated device and may be applied at continuous currents up to its ampere rating. A 4-second minimum time delay at 500percent rating allows the A4BY to pass normal current surges and to coordinate with ground fault relays.

  • Unique dimensions prevent replacement by other fuse classes
  • Blade-stamped catalog numbers for permanent identification
