Description

The SFT125 is a single-pole, 25A modular changeover switch with a centre-off (0) position and top common point configuration. It allows manual selection between two power sources, with the common input at the top terminal and the two selectable outputs below, suitable for lighting or small load changeover applications.
The centre-off position disconnects both sources during transfer, ensuring safe changeover. The single-pole format and compact DIN rail design make it appropriate for smaller single-phase changeover applications in residential or light commercial distribution.
Part of Hager’s modular changeover switch range, the SFT125 conforms to IEC 60947-3 and is designed for DIN rail installation.
