Product Profile

EKA1 Series Smart Protection Switch combines multiple circuit protection functions, including over-voltage, under-voltage, and overcurrent. It is designed for current working environments up to 63A and is available in two versions: one with Wi-Fi communication and one without. The Wi-Fi version allows for remote control of the switch status via smartphone and enables real-time monitoring of electrical parameters such as voltage, current, and power using the Tuya app. Users can also set the thresholds of the main electrical parameters through the front panel of the device or the smartphone app. EKA1 Series Smart Switch is widely used in both home and industrial settings due to its easy installation and user-friendly operation and can be wired to any existing DB or distribution board.
