قاطع العزل الثلاثي (ABB) بتيار (40A)

The ABB 40A 3P Isolator is a three-phase electrical isolator rated for 40 A. It is used to safely disconnect circuits and isolate the power supply for maintenance or testing, providing a clear break and preventing accidental energization.

Key specs include a three-phase design, 40 A current rating, double-pole operation (disconnecting both line and neutral), a red handle for easy identification, EN 60947-3 certification, and suitability for industrial and commercial use, including hazardous area applications.

It is certified to EN 60947-3 and is described as suitable for use in hazardous areas, designed to work with other safety devices like RCDs and MCBs.

The double-pole design disconnects both the live and neutral conductors, ensuring complete circuit isolation and reducing the risk of live exposure during maintenance.

Commonly used in electrical panels for industrial or commercial applications to safely isolate power during maintenance, equipment changes, testing, or shutdowns, often alongside protective devices like RCDs and MCBs.

Install the isolator in a suitable enclosure, mount it securely, and connect the supply and load to the correct poles. Ensure the power is off during installation and follow EN 60947-3 guidelines. Use appropriate mounting hardware and ensure proper cable sizing for 40 A.

Perform regular visual inspections for corrosion or wear, ensure the red handle operates smoothly and clearly indicates the off position, and verify the device remains securely mounted.
