The slow-blow fuse, also known as a time-delay fuse, is designed to handle temporary current surges while providing protection against prolonged overloads. It allows non-fault pulse currents to pass during circuit startup without blowing, which is essential in circuits where inrush or surge currents can be several times higher than normal operating current. These high currents occur for a very short duration during switching. Standard fuses may fail under such conditions, preventing normal operation. Using a larger standard fuse would compromise overload protection. The time-delay fuse features a specially engineered element that absorbs energy effectively, enabling it to withstand inrush currents and still provide reliable protection during sustained overloads.
