OT25F4N1 disconnect switch — 25 A, 4-pole Model: 10136476 Product code: 1SCA105055R1001 Series: OT (rated range 16–160 A) Key benefits - Positive isolation for safety: 4-pole disconnect provides full isolation of three-phase circuits plus neutral, reducing risk during maintenance and troubleshooting. - Right-sized protection: 25 A rating gives clear, reliable switching capacity for low- to mid-power circuits within the OT series range. - Series compatibility: Designed for installations using OT series switchgear (16–160 A), simplifying parts selection and replacement. - Streamlined panel integration: 4P configuration consolidates switching of all conductors in one device, reducing wiring complexity and potential error points. - Robust and dependable operation: Built to meet the functional expectations of industrial and commercial electrical installations. Function and important attributes - Function: Manual disconnect switch for making or breaking a circuit and providing a visible point of isolation. - Configuration: 4P (four poles) — suitable for three-phase systems with neutral. - Current rating: 25 A (part of OT series covering 16–160 A). - Identification: OT25F4N1, model number 10136476, product code 1SCA105055R1001. - Compatibility: Intended for use in OT series installations and with corresponding mounting and accessory options supplied for that series. Performance and practical considerations - Use the OT25F4N1 where a clear mechanical disconnect is required for safety and compliance. - Ideal when a single device needs to interrupt all phase conductors and neutral simultaneously. - Select this 25 A variant when load and coordination calculations call for a disconnect in the 16–160 A family but require the lower 25 A rating. Typical applications - Motor and drive maintenance: Isolate a three-phase motor or its control circuits (including neutral) before maintenance work to ensure safe servicing. - Distribution and control panels: Provide a local, visible disconnect for small feeders, branch circuits, or equipment circuits within commercial or industrial switchboards. - Equipment changeover and testing: Use as the isolation point when swapping or testing machinery or control equipment that requires interruption of all phases and neutral. Ordering and identification - Reference OT25F4N1 when specifying a 25 A, 4-pole OT series disconnect. - Use model number 10136476 and product code 1SCA105055R1001 for procurement, replacement, or inventory tracking. Note: Stay within applicable electrical codes and perform installation and maintenance per manufacturer instructions and local regulations.
