Hager LSN403 Modular Fuse Base 3P 25A 500V for 8.5x32mm Fuses

The Hager LSN403 is a robust 3-pole modular fuse base engineered for the secure housing of 8.5x32mm cylindrical fuses. Designed for integration into electrical distribution boards, this component ensures reliable circuit protection and safe manual disconnection. Its compact modular design allows for efficient space utilization within electrical cabinets, making it a dependable choice for maintaining system integrity in various professional installations.

Advantages

This fuse base offers a high level of operational safety by providing a secure mounting point for fuses, which helps prevent accidental contact with live parts. The modular construction facilitates quick and easy installation on standard DIN rails, significantly reducing assembly time. Its durable build quality ensures long-term performance under standard electrical loads, while the 3-pole configuration allows for simultaneous disconnection of three phases, enhancing control and safety during maintenance procedures.

Suitable for

• Industrial electrical distribution systems
• Commercial building power management
• Control panels requiring compact fuse protection
• Protection of auxiliary circuits

This product may not be suitable for applications requiring high-speed fuse monitoring or remote signaling capabilities, as it does not feature integrated status indicators. It is also not intended for use in environments exceeding its rated voltage or current specifications, nor is it designed for outdoor installations without an appropriate protective enclosure.

Key specifications

• Number of poles: 3
• Rated current: 25A
• Rated voltage: 500V
• Compatible fuse size: 8.5x32mm
• Mounting type: DIN rail

To use the Hager LSN403, mount the base onto a standard DIN rail within your distribution board. Insert the appropriate 8.5x32mm cylindrical fuses into the designated slots, ensuring they are seated firmly. Once installed, the device acts as a secure holder for the fuses, allowing for easy replacement when necessary. Always ensure the power supply is disconnected before inserting or removing fuses to prevent electrical hazards.

What to consider before purchase

• Verify that the fuse size matches the 8.5x32mm requirement
• Ensure the electrical load does not exceed the 25A rating
• Confirm that the installation environment is dry and protected
• Check that the DIN rail space is sufficient for a 3-pole modular unit

Usage recommendations

Always use fuses with the correct amperage rating for your specific circuit requirements to ensure optimal protection. Regularly inspect the fuse base for signs of wear or heat damage during routine maintenance checks.
