Class G Fuses

Class G fuses are current-limiting fuses designed for branch circuit protection. Class G fuses provide reliable overcurrent protection by interrupting excessive electrical flow caused by overloads and short circuits, reducing the risk of equipment damage and electrical fires. These fuses have a moderate interrupting rating and are available in various ratings to suit different applications. They are commonly used in residential, commercial, and light industrial electrical systems. LiveWire Electrical Supply carries a range of Class G fuses, including fast-acting, time-delay, and specialty fuses from Bussmann.
