Description
About the Product
The Lauritz Knudsen C-Line Manual Changeover Switch FR1 63A 4P 415V AC with SS (stainless steel) enclosure is a dependable switching solution designed for safe transfer of electrical load between two power sources such as mains supply & generator backup.
Unlike open execution models, this version comes with a robust stainless steel enclosure, offering enhanced protection against dust, moisture, & environmental conditions. Combined with an extended handle mechanism, it allows easy external operation without opening the enclosure, ensuring both convenience & safety.
The 4-pole (4P) configuration ensures complete isolation of all conductors including neutral, making it suitable for applications requiring high safety & uninterrupted power management.
