Legrand 037181 Viking Disconnectable Terminal Block for 5x20mm Fuses, 2.5mm²

The Legrand 037181 Viking disconnectable terminal block is a professional-grade component engineered for secure circuit protection in industrial electrical installations and control panels. Designed specifically to house 5x20mm fuse inserts, this terminal block provides a reliable and organized solution for modular wiring systems, ensuring that individual circuits can be easily isolated for maintenance or safety purposes.

Advantages

This terminal block is constructed from high-quality V2 polyamide, meeting strict IEC EN 60695-2-11 standards for fire resistance up to 960°C. Its design allows for significant flexibility in installation, as it is compatible with both rigid and flexible copper cables. The unit features a space-saving design that maintains a consistent height across the Viking range, resulting in a clean and professional appearance within electrical cabinets. Furthermore, the disconnection mechanism is highly versatile, allowing for operation via a blade-type lever, handle lever, or a mini lever requiring a tool, which enhances safety by preventing accidental activation.

Suitable for

• Industrial control panels
• Modular electrical distribution systems
• Circuit protection for sensitive equipment
• Applications requiring frequent maintenance or isolation of specific circuits

This terminal block may not be suitable for high-current applications exceeding the capacity of a 2.5mm² cross-section or for environments where the fuse size differs from the standard 5x20mm format. It is also not intended for use in non-standard rail systems that do not comply with EN 60715 specifications.

Key specifications

• Cross-section: 2.5mm²
• Fuse compatibility: 5x20mm
• Material: V2 polyamide (960°C fire resistance)
• Rail compatibility: 15mm depth, EN 60715 (7.5mm and 15mm depth)
• Connection type: Single connection with disconnection lever
• Bridging: Facility for 2 bridging combs

To use the Legrand 037181, mount the terminal block onto a compatible DIN rail. Insert the appropriate 5x20mm fuse into the designated holder. Connect your copper wiring, ensuring the cable is stripped to the correct length for the 2.5mm² terminal. Use the integrated lever mechanism to disconnect the circuit when maintenance is required. The block supports the use of bridging combs if multiple terminals need to be linked together.

What to consider before purchase

• Verify that your fuse size is exactly 5x20mm
• Ensure your rail system meets the EN 60715 standard
• Check that the 2.5mm² cross-section is sufficient for your specific load requirements
• Confirm the available space in your control panel for the terminal block dimensions

Ensure that all electrical installations are performed by qualified personnel in accordance with local safety regulations. Always verify that the circuit is de-energized before performing maintenance or replacing fuses.
