Hager SF263 63A 2-Pole Changeover Switch (I-0-II)

The Hager SF263 is a 63A 2-pole modular changeover switch designed to safely transfer power between two electrical sources. With its I-0-II switching configuration, the device allows manual selection between two supplies—such as mains power and a backup generator—while the centre-off position ensures complete circuit isolation during switching.

Designed for installation in consumer units or distribution boards, the switch is DIN-rail mounted and occupies 4 modules, making it suitable for compact electrical installations. It is commonly used in applications requiring safe manual switching between alternative power sources.

With a 63A rated current and durable construction, the SF263 provides reliable performance for residential, commercial, and light industrial installations where controlled power transfer is required.
