63A Dual Power Automatic Transfer Switch 2P 4P 220V CB ATS
63A Dual Power Automatic Transfer Switch — 2P / 4P, 220V CB Class ATS
Keep your home or business powered without interruption. This intelligent Dual Power Automatic Transfer Switch (ATS) seamlessly detects a loss of your primary power source and switches to the backup supply in ≤2 seconds — all automatically, with no manual intervention required. Available in both 2-Pole (2P) and 4-Pole (4P) configurations at a robust 63A rated current, it is an essential component for generators, solar backup systems, and any dual-feed electrical installation.
Key Features
- Intelligent Auto-Switching: Continuously monitors both power sources and transfers load automatically in ≤2 seconds when the primary source fails or is restored.
- CB Class Rated: Meets CB Class transfer switch standards for residential and light commercial applications.
- Dual Configuration Options: Available in 2P (single-phase) or 4P (three-phase/neutral) to suit a wide range of electrical setups.
- Wide Voltage Compatibility: Working voltage AC 220V, rated voltage AC 400V — compatible with 50 Hz and 60 Hz grid frequencies.
- Durable Plastic Housing: Compact, panel-mount-ready enclosure in white/gray finish designed for DIN-rail or breaker-panel installation.
- Fast Transfer Time: ≤2-second switching minimises disruption to sensitive appliances and electronics.

Frequently Asked Questions
Q: What is the difference between the 2P and 4P versions of this automatic transfer switch?
A: The 2P (2-Pole) version is designed for single-phase applications and controls two conductors (line + neutral), making it suitable for standard household AC circuits. The 4P (4-Pole) version controls four conductors and is used in three-phase systems or where the neutral must also be switched, common in larger residential or light commercial setups.
Q: How quickly does the ATS switch between power sources?
A: This automatic transfer switch has a transfer time of ≤2 seconds. Once it detects that the primary power source has failed or fallen outside acceptable parameters, it automatically connects the backup source within 2 seconds, minimizing disruption to connected appliances.
Q: Is this ATS compatible with solar backup and generator systems?
A: Yes. This CB Class ATS is well suited for use with generator sets, solar power backup systems, and any dual-feed electrical installation operating at AC 220V / 400V rated voltage, at 50 Hz or 60 Hz frequency.
Q: Does this transfer switch require manual intervention to switch back to the primary supply?
A: No. The intelligent switching logic monitors both power sources continuously. When the primary supply is restored and stable, the switch automatically transfers the load back — no manual toggling required.
