Hager LF590M Cylindrical Fuse 22x58 aM 100A

The Hager LF590M is a high-performance cylindrical fuse engineered for robust electrical protection in industrial environments. Measuring 22x58 mm, this component is specifically designed to handle high-current applications with a rated current of 100A. Its aM characteristic makes it an essential safety device for protecting motors, transformers, and other inductive loads that experience high inrush currents, ensuring that the system remains stable during normal operation while providing reliable disconnection during short-circuit events.

Advantages

This cylindrical fuse offers exceptional reliability and durability, which are critical for maintaining the integrity of industrial electrical distribution systems. By utilizing an aM characteristic, the fuse is optimized to withstand temporary current surges without nuisance tripping, allowing for the protection of equipment that requires high starting currents. Its compact 22x58 mm form factor allows for efficient space utilization within fuse holders and distribution boards, while the high-quality construction ensures consistent performance under demanding operational conditions.

Suitable for

• Industrial motor protection
• Transformer primary and secondary circuit protection
• Electrical distribution panels
• Heavy-duty machinery power supply systems
• Inductive load protection

When it may not be suitable

This fuse is not intended for general domestic applications or low-current household circuits where gG type fuses are typically required. It is specifically calibrated for industrial use and may not provide the appropriate protection curve for sensitive electronic equipment or standard lighting circuits.

Key specifications

• Fuse size: 22x58 mm
• Rated current: 100A
• Characteristic: aM (motor protection)
• Application: Industrial electrical systems

How to use

The Hager LF590M should be installed into a compatible 22x58 mm cylindrical fuse holder or disconnect switch. Ensure that the power supply is completely isolated before attempting to insert or replace the fuse. The fuse must be seated firmly within the clips of the holder to ensure proper electrical contact and to prevent overheating due to high resistance. Always verify that the fuse rating matches the requirements of the circuit being protected.

What to consider before purchase

• Verify that the fuse holder is compatible with 22x58 mm dimensions.
• Ensure the 100A rating is appropriate for the specific load and cable cross-section.
• Confirm that the aM characteristic is suitable for the intended application, such as motor protection.
• Check local electrical regulations regarding the use of industrial fuses.

Usage recommendations

Always replace fuses with the exact same type and rating to maintain the safety and functionality of the electrical system. Do not attempt to repair or bypass a blown fuse, as this poses a significant fire and safety risk.
