Why Choose the Mersen FR10AM40V8P Cylindrical Fuse Link?
The Mersen FR10AM40V8P is a compact 10 × 38 mm cylindrical aM fuse link designed to provide dependable short-circuit protection for motors, contactors and industrial electrical equipment. Identified by Mersen item number A084985, this fuse link has a rated current of 8 A and an IEC rated voltage of 400 V AC.
As an aM utilisation category fuse, the FR10AM40V8P provides partial-range protection against high short-circuit currents while allowing the temporary inrush currents associated with motor starting. It should be coordinated with a suitable overload relay, motor protection circuit breaker or other overload protection device to provide comprehensive motor circuit protection.
The fuse link incorporates an integrated striker mechanism that can activate a compatible auxiliary contact or indication accessory when the fuse operates. Its ceramic body, silver-plated contacts and current-limiting performance make it a reliable choice for industrial motor starters, machine control panels and electrical distribution equipment.
Key Advantages
- Compact 10 × 38 mm cylindrical fuse-link format.
- 8 A rated current for motor and industrial circuit protection.
- 400 V AC IEC voltage rating.
- aM utilisation category designed for motor circuit short-circuit protection.
- Integrated striker mechanism supports fuse-operation indication.
- High current-limiting performance helps reduce fault energy and equipment damage.
Key Features
- Mersen FR10 aM cylindrical fuse-link series.
- 10 × 38 mm fuse size.
- 8 A rated current.
- 400 V AC rated voltage according to IEC.
- aM partial-range protection characteristic.
- 100 kA AC rated breaking capacity.
- Integrated striker for use with compatible auxiliary contacts.
- Ceramic body with silver-plated electrical contacts.
Reliable Short-Circuit Protection for Motor Circuits
Industrial motors can draw several times their normal operating current during start-up. The aM operating characteristic allows the Mersen FR10AM40V8P to withstand these temporary starting currents while responding rapidly to destructive short-circuit faults.
Because an aM fuse provides partial-range protection, it does not replace a dedicated overload protection device. Coordinating the fuse with a correctly selected overload relay or motor protection circuit breaker helps protect motors, cables, contactors and associated control equipment against both overload and short-circuit conditions.
Typical Applications
- Industrial motor starters and motor control circuits.
- Contactors and overload relay assemblies.
- Pumps, fans and conveyor systems.
- Machine control panels and automation equipment.
- Industrial switchgear and distribution systems.
- OEM machinery and production equipment.
