OPAS Electric — Transfer Switch Series
Cam-operated industrial changeover switches for reliable generator/WAPDA power transfer. Detachable shaft safety interlock, quick make–quick break mechanism, IEC 60947-3 AC23 rated. Available in 2P, 3P, 4P, Phase Selector, and Neutral Cut variants from 32A to 80A.
Switching Positions
Connected to backup generator supply — powers load from gen set
Safe neutral position — panel cover can only be opened in this position
Connected to mains grid supply — normal operating position
Product Highlights
Positive cam action ensures fast, decisive switching with no intermediate position between sources.
The shaft mechanism on the panel base prevents the cover from being opened unless the switch is in the OFF (0) position — protecting against accidental live contact.
Rated for heavy inductive motor loads — suitable for industrial machinery, pumps, compressors, and HVAC equipment.
Compact footprint fits standard distribution boards and MCC panels without requiring extra enclosure space.
Robust cam construction maintains switching integrity in industrial environments with vibration from machinery.
Fully certified to IEC 60947-3 for disconnectors, isolators, and switch-disconnectors in industrial applications.
Where It's Used
Homes, commercial buildings and factories switching between mains and backup generator supply.
Motor control centres and MCC panel isolator and changeover switching for industrial machinery.
Main panel isolation and source selection in LT distribution boards and sub-main panels.
Source changeover for pumps, compressors, and HVAC equipment requiring AC23 inductive rating.
Manual source selection between solar, battery, and grid in hybrid power management systems.
