The 3-pole configuration provides simultaneous disconnection of all phases, which is essential for maintaining safety during maintenance or emergency shutdowns. Its design prioritizes ease of use and reliable contact performance, minimizing the risk of overheating and ensuring consistent power flow across the electrical system.

Suitable for

• Industrial power distribution boards
• Commercial building electrical installations
• Main circuit protection in low-voltage networks
• Systems utilizing both aluminum and copper cabling

When it may not be suitable

This device is not intended for use in high-voltage applications or environments exceeding its specified current and voltage ratings. It is also not suitable for installations where the conductor size falls outside the 16-120 mm2 range, as this would compromise the integrity of the electrical connection.

Key specifications

• Number of poles: 3
• Conductor compatibility: Aluminum and Copper
• Conductor cross-section range: 16-120 mm2
• Function: Fuse switch disconnector

How to use

Installation should be performed by a qualified electrician in accordance with local electrical codes. The conductors must be stripped to the appropriate length and securely fastened into the terminals to ensure a low-resistance connection. Once installed, the device allows for the manual insertion and removal of fuses to isolate the circuit as needed. Ensure that the device is mounted in a suitable enclosure that provides the necessary protection against environmental factors.

What to consider before purchase

• Verify that the current and voltage requirements of your system match the device specifications.
• Ensure the enclosure space is sufficient for the physical dimensions of the disconnector.
• Confirm that the conductor material and size are within the supported range.

Usage recommendations

Always ensure the circuit is de-energized before performing any maintenance or replacing fuses within the disconnector. Regularly inspect the terminal connections for signs of wear or loosening to maintain optimal performance.
