ABB OT40FT4N2 4 pole 40 A front operated door mounted switch disconnector with protected clamp terminals for industrial isolation and control panel applications.
£55.13
The ABB OT40FT4N2 is a compact and dependable 4-pole switch disconnector designed for safe electrical isolation in industrial control panels, machinery and low voltage distribution systems. As part of the trusted ABB OT switch disconnector range, it provides reliable manual switching for non-fusible disconnect applications.
This front-operated switch disconnector is designed for door mounted installation, making it ideal for control panels where external operation from the enclosure door is required. Protected clamp screw terminals provide secure electrical connections, while the compact design allows efficient use of valuable enclosure space. The operating handle and shaft are supplied separately, allowing the installation to be tailored to the application.
With a rated operational current of 40 A and a 4-pole configuration, the OT40FT4N2 is suitable for isolating three-phase plus neutral circuits in machinery, motor control centres, distribution panels and automation systems. The fourth pole is switched simultaneously, making it ideal for applications requiring neutral isolation.
The ABB OT40FT4N2 provides dependable manual isolation for industrial electrical installations, allowing equipment to be safely disconnected during servicing, maintenance and commissioning. Its quick-make, quick-break mechanism delivers reliable switching performance while helping protect personnel and equipment.
Its compact design and door mounted operation make the OT40FT4N2 particularly suitable for modern control panels where reliable three-phase plus neutral isolation is required.
