Reliable Door Mounted Isolation for Industrial Panels

Switch disconnectors such as the ABB OT100FT4N2 provide a safe and reliable method of isolating electrical circuits during maintenance, inspection and servicing. By allowing the supply to be manually disconnected, they help protect personnel and equipment while supporting safe working procedures in industrial installations.

The OT100FT4N2 is particularly useful where a 4-pole arrangement is required, such as systems needing neutral switching alongside three-phase isolation. Its front operated, door mounted format enables convenient external operation while keeping live components enclosed within the panel.

Typical Applications

• Industrial control panels and switchboards.
• Door mounted machinery isolation.
• Motor control centres and automation cabinets.
• Three-phase systems requiring neutral switching.
• Low voltage power distribution systems.
• OEM machinery and panel building applications.
