Description

The SF263 is a 2-pole, 63A modular changeover switch with I-0-II positions, allowing manual selection between two supply sources for single-phase circuits. The centre-off (0) position ensures both sources are disconnected during changeover, providing safe source transfer.
Designed for DIN rail installation, the SF263 is used in applications requiring manual changeover between a main supply and a standby generator or alternative source for single-phase circuits. The 63A rating is appropriate for domestic and small commercial incomer changeover.
Conforming to IEC 60947-3, the SF263 is part of Hager’s modular changeover switch range and is compatible with standard DIN rail distribution board accessories.
