These fuses are newly UL-listed, and are intended for applications needing Class L fuse dimensions with ampere ratings of less than 601 A.
Amp-Trap 2000 A4BQ 100-A to 600-A fuses are newly UL-listed, and are intended for applications needing Class L fuse dimensions with ampere ratings of less than 601 A. Suitable for branch circuit protection, and with Class J fuse performance, these fuses meet three specific applications: ensuring flexibility on new construction projects and future expansions; providing an acceptable and safe solution for facilities that reduce power consumption by downsizing or consolidating; and meeting arc flash mitigation needs.
The fuses were designed dimensionally for one-way interchangeability, meaning a Class L fuse of any lower ampere rating can be substituted for a given Class L fuse. These fuses reduce the risk of change orders and save time and money by using a single fuse class, switch or holder for all development plans, minimizing excess inventory and part numbers.
Downsizing and consolidation often results in reduced power consumption, forcing facilities to install unlisted products into existing switchgear or replace existing service equipment. These fuses can be used to replace replace existing 601-6000 A Class L fuses while retaining the UL listing.
The new fuses also provide optimal overcurrent protection to service entrance equipment, large motors, feeders and other circuits. They reduce the magnitude and duration of faults for better arc flash mitigation. Installing these fuses where oversized Class L fuses presently exist reduces both personal protective equipment requirements and the industrial panel’s hazard category.
