Hager LE27P20 Calibration Insert for DII 20A Fuse

The Hager LE27P20 is a precision-engineered calibration insert designed specifically for DII 20A fuses with an E27 base. This essential electrical component serves as a mechanical safeguard within distribution boards and fuse holders, ensuring that only the correct fuse rating can be installed. By preventing the accidental insertion of higher-rated fuses, it significantly enhances the safety and integrity of electrical circuits in both residential and commercial environments.

Advantages

The primary benefit of the Hager calibration insert is its ability to enforce strict adherence to circuit design specifications. Its robust construction ensures a secure and stable fit within standard E27 fuse bases, minimizing the risk of loose connections or electrical arcing. By utilizing this insert, installers can effectively prevent over-fusing, which is a common cause of electrical hazards and damage to wiring systems. The compact design allows for seamless integration into existing electrical panels without requiring additional space or complex modifications.

Suitable for

• Residential electrical distribution boards
• Commercial fuse boxes using DII systems
• Preventing incorrect fuse rating installation
• Standardizing circuit protection in E27 bases

This product is not suitable for use with fuse types other than the DII standard or for bases that do not utilize the E27 thread. It should not be used in systems where the required current rating differs from the 20A specification, as it is physically calibrated to accommodate only the designated fuse size.

Key specifications

• Fuse type: DII
• Rated current: 20A
• Base size: E27
• Width: 24 mm
• Height: 24 mm

To install the Hager LE27P20, ensure that the main power supply to the distribution board is switched off. Insert the calibration piece into the E27 fuse base and tighten it securely using the appropriate tool. Once the insert is firmly in place, the corresponding 20A DII fuse can be screwed into the base. Always verify that the insert is fully seated before restoring power to the circuit.

What to consider before purchase

• Verify that your existing fuse holder is compatible with the E27 DII standard
• Confirm that the circuit requires a 20A protection rating
• Ensure the physical dimensions of 24 mm by 24 mm fit your specific fuse base housing

Always confirm that the fuse rating matches the circuit requirements before installation. Do not attempt to modify the calibration insert, as this may compromise its safety function and lead to improper circuit protection.
