Mersen’s A4BQ Class L Fuses Reduce Arc Flash Incident Energy


Mersen’s UL Listed branch circuit fuses are highly recommended for arc flash energy reduction because they have the highest degree of current limitation. The Mersen A4BQ fuses perform well in the field when limiting arc flash incident energies to very low values for arc fault currents within their current-limiting range. They were originally designed for applications greater than 600 amperes. They offer an interrupting rating of 300 kA and a unique design that delivers excellent performance in arc flash situations. The hole pattern and blade size on this fuse are designed so that you can downsize ampere frame size easily without the need to use any reducing hardware.
