Learn more by watching our HAGER SF263 | Changeover Switch 2 Pole 63 Amp video.
The Hager SF263 is a two-pole changeover switch rated 63A at 240V, designed to manually switch power supply between the main grid and a generator or alternate source. The SF263 features zero-position contact design that prevents backfeed to the generator circuit, meeting safety requirements for dual-supply installations. It is mounted on 35mm DIN rail and complies with standard electrical requirements for changeover switching in residential and light commercial applications.
Generator backup installations commonly require reliable manual switching between mains and standby supply to protect the inverter or generator from unexpected reverse current. The SF263 solves this with a zero-position off-centre action that ensures neither source is live during the transition between mains and generator. Electricians value the switch's robust construction and clear terminal labelling, which reduce installation time and the risk of miswiring on the job site.
Licensed electricians specify the SF263 because it delivers predictable three-position switching (Mains-Off-Generator) on every cycle, with mechanical durability rated for thousands of manual operations. The switch fits standard DIN rail boards without modification and integrates seamlessly with 63A circuit protection, making it a cost-effective upgrade for retrofit generator installations where existing board space is limited.
The Hager SF263 is not suitable for automatic changeover applications or for switching three-phase supplies; those require different switch types and control logic. It is also not rated for outdoor or weatherproof installations — the SF263 is designed for indoor switchboard mounting only.
Verified Sparky Direct customer reviews: Hager Changeover Switch 2 Pole 63 Amp (SF263)

(SF263)
The Hager SF263 is a manual changeover switch that allows you to switch your home's electrical supply between the main grid and a generator or alternate power source. It features a zero-position contact design that prevents accidental dual connection and is rated for 63A at 240V single-phase supply.
Installation of the SF263 must be performed by a licensed electrician. The switch connects to the main supply circuit and requires proper terminal connection and integration into your switchboard under AS/NZS 3000 electrical standards.
No. The SF263 is designed for single-phase 240V supply only. For three-phase switching applications, you need a different changeover switch rated for three-phase operation.
The SF263 accepts rigid copper cable up to 25mm² and flexible conductor up to 16mm² at each terminal. Most residential generator circuits use 10mm² or 16mm² cable, which fit comfortably within this range.
The SF263 is rated for 100,000 mechanical operations and 5,000 electrical operating cycles at full load. This means you can safely switch daily for decades in a typical residential standby generator setup.
Yes. The SF263 comes with a two-year manufacturer's warranty covering domestic and commercial use. The warranty is void if the device is not installed by a licensed electrician.
The Hager SF263 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.
