The Allen-Bradley 155621 line fuse is specifically designed for Series A 1395 DC Drives, capable of handling 230 to 460 Volts DC with a current rating range of 20 to 56 Amps. It acts as an essential protective component, installed in triplets on each 1395 DC drive to guard against phase short circuits. Constructed with a wire isolated by a ceramic cartridge, the 155621 interrupts the power supply when necessary to prevent damage, supporting optimal use in systems with a minimum line impedance of 3%, or alongside an isolation transformer for systems with lower impedance. Suitable also for other devices within operating limits, this fuse provides reliable protection against excessive current spikes.
