Hager L502PV Modular PV Fuse Base 2P 10x38mm 32A 1000V DC

The Hager L502PV is a professional-grade modular fuse base specifically engineered for the protection of photovoltaic installations. This 2-pole device is designed to house 10x38mm cylindrical fuses, providing a robust solution for managing DC electrical circuits in solar energy systems. With a rated current capacity of 32A and a voltage rating of 1000V DC, it ensures reliable operation and safety in demanding solar power environments.

Advantages

The primary advantage of this modular fuse base is its specialized design for high-voltage DC applications, which are common in modern solar arrays. Its modular construction allows for easy integration into standard distribution boards, facilitating a clean and organized installation. The unit is built to withstand the specific electrical stresses associated with photovoltaic systems, offering consistent performance and long-term durability. By providing a dedicated housing for fuses, it enables quick and safe maintenance or replacement of protection elements without disrupting the entire system architecture.

Suitable for

• Photovoltaic string protection
• Solar energy distribution boards
• DC electrical circuit management
• Residential and commercial solar installations

When it may not be suitable

This fuse base is strictly intended for DC applications and should not be used in AC electrical circuits. It is not compatible with fuse sizes other than the specified 10x38mm format.

Key specifications

• Number of poles: 2
• Compatible fuse size: 10x38mm
• Rated current: 32A
• Rated voltage: 1000V DC
• Mounting type: Modular/DIN rail

How to use

The Hager L502PV is designed for mounting onto a standard DIN rail within an electrical enclosure. Installation should be performed by a qualified professional in accordance with local electrical regulations. Once mounted, insert the appropriate 10x38mm DC-rated fuses into the holders. Ensure that all connections are tightened to the specified torque to prevent overheating and ensure optimal electrical contact. The modular design allows for side-by-side mounting if multiple strings require protection.

What to consider before purchase

• Verify that the system voltage does not exceed 1000V DC
• Ensure the fuse size matches the 10x38mm requirement
• Confirm that the 32A current rating is appropriate for your specific solar string configuration
• Check available space in your distribution board for a 2-pole modular unit

Usage recommendations

Always use fuses specifically rated for DC photovoltaic applications to ensure the safety and integrity of your solar installation. Regularly inspect the fuse base for signs of wear or thermal stress during routine maintenance.
