Glass Fuse 125mA 250V AC
The EATON BUSSMANN GMD series fuse provides circuit protection for low-current equipment rated at 125 mA and 250 V AC. It suits maintenance technicians and hobbyists who need reliable overcurrent protection for instrumentation or control circuits. The time-delay characteristic tolerates brief inrush currents without nuisance opening. Buyers needing higher current ratings or different voltage classes should select another part.
Interrupt Ratings 100A at 250V AC 10kA at 125V AC
The fuse interrupts up to 100 A at 250 V AC and 10 kA at 125 V AC, giving ample margin for typical panel-mounted power supplies and small transformer primaries. It runs out of headroom on circuits with prospective fault currents above those values or on systems exceeding 250 V AC. The single-element construction ensures predictable clearing times within the GMD series envelope.
20mm x 5mm Cylindrical Glass Body Pack of 5
The cylindrical glass body measures 20 mm long by 5 mm diameter and fits standard HTB series fuse blocks with non-rejection mounting. Glass construction allows visual inspection of the element after a fault. The pack contains five fuses, convenient for spares or multi-point protection. Installations requiring rejection-style holders or ceramic bodies will need a different fuse series.
