Switching Positions

1 — 0 — 2 : Generator · OFF · Grid

1

Generator

Connected to backup generator supply — powers load from gen set

0

OFF

Safe neutral position — panel cover can only be opened in this position

2

WAPDA / Grid

Connected to mains grid supply — normal operating position

Key Features

Quick make — quick break cam mechanism

Positive cam action ensures fast, decisive switching with no intermediate position between sources.

Detachable shaft safety interlock

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.

AC23 rated for inductive loads

Rated for heavy inductive motor loads — suitable for industrial machinery, pumps, compressors, and HVAC equipment.

Compact panel-mount design

Compact footprint fits standard distribution boards and MCC panels without requiring extra enclosure space.

Unaffected by vibration and shock

Robust cam construction maintains switching integrity in industrial environments with vibration from machinery.

IEC 60947-3 compliant

Fully certified to IEC 60947-3 for disconnectors, isolators, and switch-disconnectors in industrial applications.

Applications

Generator / WAPDA Changeover

Homes, commercial buildings and factories switching between mains and backup generator supply.

Industrial Motor Control & MCC Panels

Motor control centres and MCC panel isolator and changeover switching for industrial machinery.

Distribution & Main Control Panels

Main panel isolation and source selection in LT distribution boards and sub-main panels.

Pump Control & HVAC Systems

Source changeover for pumps, compressors, and HVAC equipment requiring AC23 inductive rating.

Solar Hybrid Power Switching

Manual source selection between solar, battery, and grid in hybrid power management systems.
