Why Choose the Mersen FR14AM69V8 Cylindrical Fuse Link?
The Mersen FR14AM69V8 is a high-performance aM cylindrical fuse link engineered to provide reliable short-circuit protection for motor circuits and industrial electrical equipment. As part of the trusted Mersen 14 × 51 mm ferrule fuse range, it is specifically designed for applications where motors generate high starting currents and require dependable fault protection without nuisance operation.
Manufactured with a robust ceramic body and silver-plated contacts, the FR14AM69V8 offers excellent current-limiting characteristics and a high breaking capacity. Its aM operating characteristic allows motor starting currents to pass while rapidly interrupting damaging short-circuit currents, making it ideal for coordinated motor protection systems.
With a rated current of 8 A, a 690 V AC rating and a compact 14 × 51 mm IEC format, the FR14AM69V8 is well suited to motor starters, control panels, switchgear and OEM machinery operating in demanding industrial environments.
