Schneider Electric LK3-BC4 Isolator Disconnect Switch

The Schneider Electric Telemecanique LK3-BC4 is a three-pole, 160 A isolator disconnect switch rated for up to 750 VAC, designed for safe manual isolation of industrial power circuits. This non-fusible, load-break/disconnect device is panel-mount with a rotary handle and operates at 50/60 Hz, making it suitable for use in motor control centers, industrial control panels, process automation systems, and power distribution cabinets. It functions as an OEM direct replacement for LK3 installations and has common replacements such as the Schneider Electric INS160 Switch Disconnector, making it a practical choice for equipment retrofit projects, preventive maintenance, and new panel installations in three-phase environments.
