Mersen Ferraz A4BY1000 Current-Limiting Fuse, 1000Amp

Mersen Ferraz A4BY1000 Current-Limiting Fuse

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.
