• Automatic three‑phase switching: Automatic transfer switch manual transfer switch monitors L1–L3 and instantly switches to a healthy phase or a designated priority phase when overvoltage, undervoltage or overcurrent is detected — protects connected equipment from damage; manual control lets you override automation and lock to L1 or L2
• Adjustable protection thresholds: Default settings of Automatic transfer switch circuit breaker box suit most installations; OV, UV and OC trip points and delays are user‑adjustable for tailored protection of grids, inverters and generators
• Real‑time monitoring & manual override: Built‑in screen of Automatic transfer switch low voltage cutoff displays incoming phase voltages, output voltage and output current; color status lights show normal/fault conditions
• Robust electrical & mechanical design: 63A rated 4‑pole automatic transfer switch with large tunnel terminals (14–4 AWG / 1.5–25 mm²), flame‑retardant PA66 shell and corrosion‑resistant contacts for long service life in harsh environments
• Easy DIN Rail Mounting: Automatic transfer switch comes with mounting clips that allow for secure attachment to standard 35mm DIN rails (rail not included), ideal for crowded panels, RV power centers, solar systems, telecom racks, and cabinet retrofit installations
• Automatic transfer switch is applicable to home backup power, generator/inverter integration, industrial production lines and motor control circuits, traffic signal and public infrastructure power protection, medical facilities and data center branch protection, E‑bike / battery system protection and charger/inverter safeguarding...
