Suntree SQ8W-63 63A 4-pole ATS
Suntree SQ8W-63 63A 4-Pole Automatic Transfer Switch
The Suntree SQ8W-63 Automatic Transfer Switch (ATS) is designed to transfer an electrical load between a normal power source and a standby source when the primary supply fails or returns, according to its configured operating mode.
With a 63A current rating and four-pole switching, this model is suitable for compatible three-phase AC installations where the neutral conductor also needs to be switched. It can be considered for appropriately designed solar inverter, utility mains and generator backup systems.
Key Features
- 63A rated current: For compatible electrical installations designed within the switch's ratings.
- Four-pole switching: Switches the three phase conductors and neutral in compatible systems.
- Automatic power transfer: Helps maintain supply by changing over between two power sources.
- Manual operation: Check the exact model's operating instructions for manual selection and control.
- AC supply compatibility: Manufacturer specifications list AC 230V/400V operation for the SQ8W series.
- Compact transfer-switch design: Intended for installation in a suitable electrical enclosure.
- Backup power applications: Suitable for correctly designed mains, generator and compatible inverter arrangements.

- Compatible solar inverter and utility backup systems
- Commercial and residential backup power
- Electrical distribution panels requiring automatic source changeover
- Other compatible AC installations with two power sources
Installation and Safety Notes
This is an AC transfer switch, not a solar-panel DC isolator. Confirm that both power sources, the load, neutral arrangement and earthing system are compatible with the four-pole device. Verify whether the connected inverter or generator permits the intended neutral switching arrangement.
The switch should be installed by a qualified electrician. Correct upstream overcurrent protection, fault-current coordination and isolation are essential. Do not assume that the ATS alone provides all required circuit protection; verify the protection features of the exact model and installation design.
