Eaton 4A T Melamine Cartridge Fuse 10 x 38 mm 250V AC Time Delay FNM-4

Eaton FNM-4 4A T Melamine Cartridge Fuse offers reliable time-delay overcurrent protection at 250V AC for electrical circuits requiring transient tolerance and sustained overload interruption. Featuring a melamine body, it provides excellent insulation and mechanical stability in demanding industrial and electronic installations.

This fuse utilizes a slow-blow (T-speed) characteristic, allowing it to withstand short-term current spikes such as motor start-ups without nuisance blowing, while effectively protecting circuits against prolonged overloads at a 4A current rating.

The compact cylindrical format of 10 x 38 mm is compatible with standard fuse holders and clips, facilitating easy installation and maintenance replacement. It conforms to UL 248-14 standards, ensuring recognized performance and safety.

Applications include control panels with inductive loads, transformers, motor control circuits, and automation equipment that experience start-up current surges. It is widely used in industrial, commercial, manufacturing, and electrical automation contexts for effective circuit protection.

Time-delay characteristic tolerates transient surges without nuisance blowing. Rated current of 4A supports protection of low-current circuits. T-speed (slow-blow) prevents fuse blowing during motor start-ups. Compact cylindrical 10 x 38 mm format fits standard holders.

Melamine body ensures robust insulation and dielectric stability. Designed for 250V AC applications in industrial and commercial settings. Complies with UL 248-14 recognized fuse performance standards. Ideal for control panel protection with inductive loads and motor circuits.
