Automatic Transfer Switch 63A 4P 3PH Overcurrent Overvoltage Undervoltage Protector ATS Adjustable Circuit Breaker LED

Feature: 1. THREE PHASE SWITCHING: Automatic transfer switch features voltage display, current display, automatic switching, overvoltage protecting, undervoltage protecting, overload protecting, and supports three phase voltage switching 2. MULTIPLE PROTECTIONS: Always safeguarding your household appliances. When overvoltage, undervoltage and overcurrent are detected in the current phase, ATS automatically switches to other phases to restore normal power supply and automatically switches to the priority phase, thereby protecting electrical equipment from damage. By default, under voltage tripping occurs when the voltage is less than 170V, and by default, over voltage tripping occurs when it is more than 270V 3. ADJUSTABLE THREE LAYER PROT
