North American Power Fuses

North American Power Fuses The most popular North American power fuses to meet the most popular protection priorities. Your problem: Today, you need a time-delay power fuse that can handle normal surges. Tomorrow, it s a power fuse with a high interrupting rating and the added security of rejection dimensions. The day after that, one of those economical one-time power fuses will do the trick. ut where can you turn for all three? Our solution: Ferraz Shawmut s comprehensive power fuse offering covers a complete range of applications and a complete range of circuit-protection needs. Whether it s the characteristics of our Tri-onic time-delay fuses. The high current-limiting capacity of our original Amp-trap power fuses. The cost-efficient protection of our One-Time fuses. Or some other application-specific power fuse solution. Want more information fast?

A4Y CLASS l count on the high interrupting rating of our most widely-used class L fuse When it comes to protecting service entrance equipment, feeder circuits, and circuit breakers, A4Y fuses have been the industry s favorite. The A4Y 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 A4Y to pass normal current surges and to coordinate with ground fault relays.

HSRK high speed/class rk1 High speed rk1 (HSRK) Protect your electrical power wiring and power semiconductors with a single fuse. The new HIGH SPEED RK1 (HSRK) combines semiconductor fuse performance with NEC branch circuit compliance. The fuse was designed with two specific applications in mind: 1. To provide semiconductor fuse performance to solid state drive applications but in the larger RK body sizes that have been typically installed in older systems. 2. To provide industrial power applications with the most current limiting fuse available, which in turn provides the best arc flash mitigation available to power systems using the larger RK size fuses. Highlights: Current Limiting Low I 2 t Drive protection in larger RK body sizes for older installations Fast acting Applications: ranch circuits AC drives Solid state controllers Feeder circuits Arc flash mitigation Features/enefits Most current limiting RK1 available Provides the best Arc flash mitigation for feeder and branch circuits (non motor load circuits) Excellent cycling ability for frequent drive starts and stops without nuisance opening Extremely Low I 2 t Ratings AC: (70 to 600A) 600VAC, 200KA I.R. 300KA I.R.
