## Overview

The 4PRO ATS-63A-4P Automatic Changeover Transfer Switch is engineered for seamless power management, boasting a robust 63A capacity and compatibility with various generator types. With true RMS measurements and an external voltage adjustment feature, this switch ensures precision and reliability for your power needs.

## Description

The ATS-63A changeover switch is designed to transfer loads automatically and manually from one power source to another in a wide variety of 1-3 phase applications.  FEATURES: - A design based on 63A automatic circuit breakers; - Motorized or manual mode switching; - 2-3 phase operation, 4 pole; - Built-in mechanical and electrical interlocking; - 3-position manual switching handle (Main-OFF-Reserve); - High reliability due to stable positions of the change-over mechanism energized during switching process only; - Internal position indication lamps and externallamp outputs; - Input protection fuses.  Device monitors mains and generator control phase voltage. In case if there is the mains control phase voltage, the device connects the load circuits to the mains inputs. If the mains control phase voltage is lost, the device comes to a waiting mode keeping the load circuits connected to the mains inputs. In case if, there is the generator control phase voltage (while mains control phase voltage is absent), the device connects the load circuits to the generator inputs. If the generator control phase voltage is lost, the device comes to a waiting mode keeping the load circuits connected to the generator inputs. In case if the mains control phase voltage is recovered, the device connects the load circuits to the mains inputs independently on having the generator control phase voltage or not. If the Auto mode switch in the OFF position, you could switch the load circuit connection between mains and generator inputs manually. Mains inputs always have priority.
