11 There are many advantages to using these fuses. Unlike single-element fuses,the Cooper Bussmann dual-element, time-delay fuses can be sized closer toprovide both high performance short circuit protection and reliable overloadprotection in circuits subject to temporary overloads and surge currents. ForAC motor loads, a single-element fuse may need to be sized at 300% of anAC motor current in order to hold the starting current. However, dual-element,time-delay fuses can be sized much closer to motor loads. For instance, it is generally possible to size Fusetron dual-element fuses, FRS-R and FRN-Rand Low-Peak dual-element fuses, LPS-RK_SP and LPN-RK_SP, at 125%and 130% of motor full load current, respectively.
