DESCRIPTION

The GMC-4A is a UL-rated 5 x 20mm medium time-delay glass tube fuse designed for circuit protection in consumer electronics and appliances. This fuse features a 4A current rating and is part of the Cooper Bussmann GMC series, which provides reliable overcurrent protection with time-delay characteristics that tolerate temporary inrush currents common in inductive loads. The medium time-delay design incorporates a coiled wire or thick element wrapped in wire, allowing it to distinguish between harmless transient surges and genuine fault conditions. The fuse is available in standard packaging formats and is suitable for applications requiring precise protection in household and consumer equipment operating at standard voltage ratings. Its compact 5 x 20mm form factor makes it ideal for space-constrained circuit designs where reliable, accurate protection is essential.
