Why Choose the ABB OT125FT4N2 Switch Disconnector?

The ABB OT125FT4N2 is a compact and reliable 4-pole door mounted 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 proven ABB OT Series, it provides dependable switching performance for panel builders, OEMs and electrical engineers requiring secure circuit isolation.

This front operated, non-fusible switch disconnector is designed for installations where external operation through an enclosure door is required. Its front protected clamp terminals, compact format and robust construction make it well suited to demanding industrial environments where safety, reliability and ease of installation are essential.

With a 125 A current rating, 4-pole configuration and Product ID 1SCA105066R1001, the OT125FT4N2 is ideal for three-phase systems requiring neutral isolation or additional pole switching. The operating handle and shaft are supplied separately, allowing the installation to be configured around the enclosure depth and panel layout.
