ABB OT125FT3 3-pole 125 A front operated door mounted switch disconnector for industrial circuit isolation, control panels, machinery and low voltage power distribution applications.
£112.79
The ABB OT125FT3 is a compact and reliable 3-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 applications where external operation through an enclosure door is required. Its robust construction, protected terminals and compact design make it well suited to demanding industrial environments where safe isolation, reliability and ease of installation are essential.
With a 125 A current rating, 3-pole configuration and door mounted format, the OT125FT3 is ideal for machinery isolation, control panels, motor control centres and industrial switchboards. The operating handle and shaft are supplied separately, allowing the installation to be configured around the enclosure depth and panel layout.
Switch disconnectors such as the ABB OT125FT3 provide a safe and dependable way to isolate electrical circuits during servicing, inspection and maintenance. By allowing the electrical supply to be manually disconnected, they help protect personnel and equipment while supporting safe working procedures in industrial installations.
The OT125FT3 is particularly suitable for enclosure applications where the switch body is installed inside the panel and operated externally from the door. This arrangement provides convenient access for operators while keeping live components safely enclosed within the control cabinet.
