ABB OT100FT4N2 4-pole 100 A front operated door mounted switch disconnector for industrial circuit isolation, control panels, machinery and low voltage power distribution applications.
£138.43
The ABB OT100FT4N2 is a robust and reliable 4-pole switch disconnector designed for safe manual isolation of electrical circuits in industrial control panels, machinery and low voltage power distribution systems. As part of the trusted ABB OT Series, it provides dependable switching performance for panel builders, OEMs and electrical engineers requiring secure circuit isolation.
This front operated, door mounted switch disconnector is designed for applications where external panel operation is required. Its non-fusible construction, front protected clamp terminals and compact design make it suitable for demanding industrial environments where reliability, safety and ease of installation are essential.
With a 100 A current rating, 4-pole configuration and door mounted operation, the OT100FT4N2 is ideal for three-phase systems requiring neutral isolation or multi-pole switching. The operating handle and shaft are supplied separately, allowing the installation to be configured to suit the enclosure depth and panel layout.
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.
