Cooper Bussmann Cable Copper Limiter (600V)

. Product Features Selection: unlike fuses, the current-carrying capacity of cable limiters is denoted by cable size rather than amperage. For example, a “4/0” limiter will carry the current of a 4/0 cable. Buss Cable Limiters help protect cables against shortcircuit currents. Increase system reliability. Under high short-circuit conditions, they can cut off fault currents within one-half cycle (0.008 seconds). This fast action reduces insulation damage from the immense heat that is developed by sustained fault current flow (often 30,000, 50,000, 70,000, 150,000 amps magnitude). Reduces the high build-up of mechanical forces due to intense magnetic fields. Cable limiters help confine damage to the point of the short-circuit. Help stop long-length cable burn-back and striking of multiple arcs. Apart from the loss of power and operational shutdown, short-circuits can do devastating damage to conductors. The cost of total replacement of cables, particularly when they are buried underground, outweighs the nomi...
