Mersen Amp-Trap® A4BY1200 Current Limiting Low Voltage Time Delay Fuse, 1200 A, 600 VAC/300 VDC, 200/100 kA Interrupt, L Class, Cylindrical Body
Mains, Feeders, Circuit Breakers, Load Centers, Panelboards, Switchboards and Metering Centers Applications
RoHS Compliant | UL 248-10 | UL File No. E2137 | CSA C22.2 No.248.10 | IEC 269-2-1

Mersen Amp-Trap® Time Delay Fuse, Current Limiting Low Voltage, Series: A4BY, Non-Indicating, Rejection, 1200 A, 600 VAC/300 VDC, 200/100 kA Interrupt, Class: L, 4 s at 500% Response, Blade Terminal, Bolted-On Mounting, Cylindrical Body, Dual Element, Fiber, 2-1/2 in Dia x 10-3/4 in L Body

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.
