Learn more by watching our HAGER SF463 | Changeover Switch 4 Pole 63 Amp video.
The Hager SF463 is a 4-pole changeover switch rated 63A at 400V, designed to transfer electrical supply between two independent sources such as mains power and a backup generator. The SF463 features a screw-type connection suitable for cable cross-sections up to 25mm² (rigid) or 16mm² (flexible), and is mounted on a din rail. It complies with standard European electrical safety requirements and is approved for switching AC loads at rated current with 5,000 electrical operating cycles.
Changeover switches are essential components in installations where uninterrupted power is critical. Property owners installing generators, businesses operating backup power systems, and installers working on commercial or industrial switchboards all depend on a switch that connects mains and generator supplies without allowing current to flow between them simultaneously. The SF463 meets this need with a compact din rail design that fits into space-constrained enclosures and allows straightforward wiring with large aperture terminals.
Licensed electricians value the Hager SF463 for its simplicity and robust construction. The four poles provide flexibility when managing diverse power sources, the changeover mechanism locks out accidental switching, and the device integrates smoothly into standard switchboard layouts without requiring costly modifications. For generators paired with residential or small commercial properties, the SF463 is a proven choice that trades minimal complexity for maximum reliability.
The Hager SF463 is not suitable for outdoor, damp, or weatherproof installations. The device is rated IP20 and is designed for use inside switchboards and enclosures only. Do not install the SF463 in bathrooms, laundries, kitchens, or any location subject to moisture, salt spray, or environmental contamination without an additional protective weatherproof enclosure rated IP54 or higher.

(SF463)
Yes, the SF463 is commonly used in residential generator installations. The 63A rating suits most domestic properties with backup generators. Installation must be carried out by a licensed electrician in compliance with AS/NZS 3000 and the relevant state electrical regulations. The switch connects mains and generator supplies to the main switchboard, allowing safe switching between sources.
The SF463 accepts rigid conductor up to 25mm² or flexible conductor up to 16mm² for each terminal. The screw terminal design accommodates larger cable cross-sections without crimped lugs or reducers, making installation faster on high-current circuits.
No, the SF463 is rated IP20 and is not suitable for outdoor, damp, or weatherproof installations. The device is designed for use inside dry switchboards and enclosures only. If outdoor or damp-location installation is required, the switch must be housed in an additional protective enclosure rated IP54 or higher.
The SF463 is a manual changeover switch operated by hand, not automatic. It requires the user or electrician to physically move the handle to switch between mains and generator. Some installations also use automatic changeover switches that detect mains failure and switch to generator supply without manual intervention; however, these are more complex and costly.
Yes, the changeover mechanism includes a zero or neutral position between the mains and generator positions. This design prevents simultaneous connection of both sources, which is the primary safeguard against backfeed. However, additional safety measures such as lockable hasps or interlocked controls may be specified by the site electrical engineer or local authority.
The SF463 is rated for storage temperatures from -40°C to +80°C. Operating conditions should be within a typical indoor environment (approximately -10°C to +50°C for reliable performance). The switch must be protected from extreme heat sources or cold exposure.
The Hager SF463 is available online from Sparky Direct, with Australia-wide delivery to any state or territory including regional areas. Sparky Direct is an Australian electrical wholesaler established in 2005, supplying more than 500,000 customers with transparent trade pricing.
