MDL-12 is a time-delay glass tube fuse designed for overcurrent protection in appliances and consumer electronics applications. This fuse features a 12 amp current rating and standard 1/4" x 1-1/4" dimensions, making it compatible with common fuse holders. The time-delay characteristic allows the fuse to withstand temporary inrush currents while still providing reliable protection against sustained overloads. MDL series fuses are commonly used in applications where momentary current surges occur during startup, such as motors and transformers, providing precise circuit protection with high reliability.
