Why Choose the Mersen FR10AM69V2 Industrial aM Fuse?
The Mersen FR10AM69V2 (catalogue #J302780) is a high-performance 10×38 mm cylindrical ferrule fuse designed for robust protection of motors and transformers in low-voltage systems up to 690 VAC. Featuring a 2 A rating, aM motor-characteristic curve to tolerate start-up inrush, and a substantial 120 kA breaking capacity, it effectively isolates fault currents during short-circuits. Constructed with a reliable ceramic body and silver-plated contacts, and fully compliant with IEC 60269-1/-2, it’s trusted in control panels, switchgear, and industrial distribution networks.

Trusted by Engineers Worldwide
"Used extensively across MCC fleets—FR10AM69V2’s compact 10×38 size and 690 V rating are ideal for modern switchgear."
– Electrical Design Lead, UK OEM
aM (motor) fuses allow start-up inrush but quickly interrupt short-circuits above ~6.3×In, protecting motors and transformers from severe fault currents.
aM fuses are partial-range (ideal for motor protection), while gG fuses offer full-range protection including overloads. Choose aM for motors; gG for cable/line protection.
Yes — the 120 kA IEC rating is well-suited to most industrial LV and 690 VAC panels and MCC applications.
Yes — indicator (suffix "I") and striker (suffix "P") variants exist in the 10×38 aM series. See Mersen documentation and distributor catalogs.
Meets IEC 60269-1/2 standards, CE-marked, and RoHS-compliant — suitable for international industrial use.
