The Eti-Polam BZ-4 is a high-quality 4-pole cylindrical fuse holder engineered specifically to accommodate 5x20mm fuses. This modular device serves as a critical component for electrical distribution systems, providing a secure housing that ensures both the protection of electrical circuits and the safety of the surrounding equipment. Designed for durability and ease of use, it facilitates reliable electrical contact while allowing for quick and efficient fuse replacement during maintenance tasks.

Advantages

This fuse holder offers a robust design that guarantees stable performance in both industrial and residential environments. Its modular construction allows for seamless integration into existing electrical panels, saving space and simplifying the installation process. The materials used in its manufacturing ensure high resistance to mechanical stress and thermal fluctuations, contributing to a longer service life for the entire electrical system. Furthermore, the design prioritizes user safety by providing a secure enclosure that minimizes the risk of accidental contact with live parts during operation or fuse replacement.

Suitable for

• Industrial control panels and automation systems
• Residential electrical distribution boards
• Protection of low-voltage electronic circuits
• Maintenance and repair of electrical equipment

When it may not be suitable

This fuse holder is designed exclusively for 5x20mm cylindrical fuses and is not compatible with larger fuse types or different form factors. It is intended for specific voltage and current ratings, meaning it should not be used in high-power applications that exceed its technical specifications.

Key specifications

• Number of poles: 4
• Compatible fuse size: 5x20mm
• Mounting type: Modular/DIN rail
• Application: Low-voltage circuit protection

How to use

To install the Eti-Polam BZ-4, mount the unit onto a standard DIN rail within your distribution board. Ensure that the power supply is disconnected before inserting or replacing any fuses. Open the holder mechanism, place the 5x20mm fuse into the designated slots, and close the cover securely to establish contact. Always verify that the fuse rating matches the requirements of the specific circuit being protected to prevent damage or fire hazards.

What to consider before purchase

• Verify that your circuit requires a 4-pole configuration
• Ensure the fuse size matches the 5x20mm standard
• Check the current and voltage requirements of your installation
• Confirm compatibility with your existing distribution board layout

Usage recommendations

Always use fuses with the correct amperage rating as specified by the equipment manufacturer to ensure optimal protection and prevent system failure. Regularly inspect the holder for signs of wear or heat damage during routine maintenance.
