Why Choose the ABB OHYS1AH1 Selector Handle?
The ABB OHYS1AH1 is a genuine red and yellow selector handle designed for compatible ABB OT and OTDC switch disconnectors. As part of ABB's trusted range of low-voltage switchgear accessories, it provides safe, reliable external operation of disconnect switches while incorporating an integrated door interlock in the ON position for enhanced operator safety. It is specifically designed for switches with a 6 mm operating shaft and a 22.5 mm door cut-out.
Manufactured from robust industrial-grade materials, the OHYS1AH1 features a highly visible red handle with a yellow mounting plate, making switch status immediately recognisable. Its compact selector design is ideal for industrial control panels, machinery, OEM equipment and power distribution systems where dependable manual isolation is essential.
The handle is compatible with selected ABB OT16...40F and OTDC16...32F switch disconnectors. The integrated door interlock prevents the enclosure door from being opened while the switch is in the ON position, helping improve personnel safety during operation and maintenance.
