£34.09
The ABB OT25F4N2 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.
Designed for front operation, the OT25F4N2 supports both base mounting and DIN rail installation, providing installation flexibility for panel builders and OEM machine manufacturers. Protected clamp terminals ensure secure wiring, while the compact design maximises valuable enclosure space. The handle and shaft are supplied separately, allowing the correct operating accessories to be selected for each application.
With a rated operational current of 25 A and a 4-pole configuration, the OT25F4N2 is ideal for isolating three-phase plus neutral circuits in industrial machinery, motor control centres, switchboards and automation systems. The switched fourth pole provides simultaneous switching for neutral conductors.
The ABB OT25F4N2 provides dependable manual isolation for industrial electrical systems, allowing equipment to be safely disconnected during servicing and maintenance. Its quick-make, quick-break switching mechanism and compact modular construction make it well suited to modern electrical installations.
Designed in accordance with IEC 60947-3 and UL 508, the OT25F4N2 delivers reliable performance in machine building, motor control and low voltage distribution applications.
