Applications
This 100A 4 pole unit is a practical fit for generator panels, solar backup boards, commercial mains-to-generator transfer, and larger inverter source selection. In Faisalabad, it suits backup panels where neutral switching matters on three-phase loads. For home and commercial boards, it is usually paired with voltage protectors, SPDs, and upstream circuit breakers.
| Use case | Recommended variant | Why |
|---|---|---|
| Three-phase mains and generator transfer | 4P 100A | Switches neutral plus all three phases |
| Medium office or commercial backup board | 4P 100A | More current headroom than 63A |
| Small three-phase workshop | 3P 63A or 4P 63A | Depends on whether switched neutral is required |
How to Choose

What This Product Does NOT Protect Against
This switch does not regulate voltage, stop surge damage, trip on overload, or transfer power automatically. It is a manual source selector. Use it with the right breakers, voltage protectors, and surge protection devices.
Installation
- Mount the switch firmly in the panel.
- Mark mains, OFF, and generator positions clearly.
- Use correct cable size and torque for the 100A panel design.
- Test source transfer before load handover.
