A4BY - Class L - Time-Delay
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.
