Legrand 012004 Cylindrical Safety Fuse 4A aM 8.5x31.5mm

The Legrand 012004 cylindrical safety fuse is a high-performance component engineered to provide reliable protection for electrical circuits. With a rated current of 4A and an aM characteristic, this fuse is specifically designed to handle motor-start currents while offering robust protection against short circuits and overloads in demanding electrical environments. Its compact 8.5x31.5mm form factor allows for seamless integration into standard fuse holders, making it an essential element for maintaining safety and operational continuity in various industrial and commercial systems.

Advantages

This fuse offers exceptional reliability and precision in electrical protection. The aM characteristic ensures that the fuse can withstand temporary current surges, such as those occurring during motor startup, without nuisance tripping, while still providing rapid disconnection in the event of a genuine fault. Manufactured to meet international standards, it guarantees consistent performance and safety. Its compact design ensures space efficiency within control panels and distribution boards, facilitating easier installation and maintenance processes.

Suitable for

• Industrial motor control circuits
• Commercial electrical distribution systems
• Protection of electrical equipment against short circuits
• Applications requiring high rupture capacity

When it may not be suitable

This fuse is not intended for use in circuits requiring gG (general purpose) characteristics, as it is specifically optimized for motor protection. It should not be used in applications where the operating voltage exceeds the specified 400V limit.

Key specifications

• Rated current: 4 Amps
• Voltage rating: 400 Volts
• Dimensions: 8.5x31.5mm
• Characteristic: aM
• Rupture capacity: 20,000 Amps
• Compliance: EN 60269-1, IEC 60269-1 and 2
• Certification: Veritas approved

How to use

The fuse should be installed into a compatible 8.5x31.5mm fuse holder or disconnect switch. Ensure that the power supply is completely disconnected before attempting to insert or replace the fuse to prevent electrical shock. Align the fuse with the holder terminals and press firmly until it is securely seated. Verify that the circuit is properly rated for a 4A fuse before energizing the system.

What to consider before purchase

• Verify the current rating matches your circuit requirements
• Ensure the fuse holder dimensions are compatible with 8.5x31.5mm
• Confirm the application requires aM characteristic protection
• Check that the system voltage does not exceed 400V

Usage recommendations

Always replace a blown fuse with one of the exact same rating and characteristic to maintain the integrity of the electrical protection system. Do not attempt to repair or bypass a blown fuse.
