Why Choose the Mersen FR10AM69V12 Cylindrical Fuse-Link?
The Mersen FR10AM69V12 is an industrial aM cylindrical fuse-link designed to provide reliable short-circuit protection for motors, motor starters and associated electrical equipment. Part of the Mersen range of 10 × 38 mm ferrule fuse-links, it is suitable for use in demanding industrial circuits operating at voltages up to 690 V AC.
Its aM partial-range operating characteristic is specifically designed for motor circuit protection. The fuse-link withstands the temporary inrush currents associated with motor starting while responding rapidly to dangerous short-circuit currents. Appropriate overload protection must be provided separately by a motor protection relay, thermal overload relay or equivalent device.
With a rated current of 12 A, a compact 10 × 38 mm cylindrical format and robust ceramic construction, the FR10AM69V12 provides dependable current limitation within motor control panels, industrial machinery and automation systems. Silver-plated contacts support consistent electrical performance and reliable installation in compatible fuse holders.

Reliable Short-Circuit Protection for Motor Circuits
The Mersen FR10AM69V12 is designed to limit and interrupt high short-circuit currents before they can cause serious damage to motors, contactors, cables and other motor control equipment. Its low thermal let-through performance helps reduce the electrical and mechanical stress placed on protected components during a fault.
Because an aM fuse-link provides partial-range protection, it must be coordinated with a suitable overload protection device. This combination delivers effective protection while allowing the motor to draw the elevated current required during normal starting.
