Misopily 100Amp 220V Dual Power Automatic Transfer Switch 2P Manual Changeover Electrical Switch for Generator Solar Backup Power Overvoltage

This dual power automatic transfer switch supports seamless switching between two 220V AC power sources, handling up to 100A with both automatic and manual modes to ensure continuous and reliable power for your essential devices and systems in homes, shops, or data centers.

Engineered for maximum safety, this 2-pole switch features advanced overvoltage and undervoltage protection with precise thresholds—undervoltage at 175V, recovery at 195V, overvoltage at 260V, and recovery at 240V (±5V)—helping safeguard electrical equipment from dangerous fluctuations.

Constructed from high-strength PA6 material, this transfer switch offers excellent durability and heat resistance, making it ideal for demanding environments where consistent performance and safety are critical, while its lightweight build allows for easy installation.

Designed for 50/60Hz dual power grids, the switch fits standard PZ30 distribution boxes for straightforward integration into home, commercial, or industrial electrical systems, supporting a working current range from 6A to 100A for flexible usage scenarios.

The automatic mode continuously monitors the main power source and instantly transfers the load to the backup source within 0.05 seconds if an issue is detected, while the manual mode allows users to select the backup source with a simple switch flip for added control.

Perfect for applications where power interruptions are unacceptable, this device is suited for home protection, small businesses, medical equipment, emergency systems, uninterrupted production lines, photovoltaic microgrids, and both indoor and outdoor generator setups.
