An AC guard with the specifications 63A-230V is a protective device designed to safeguard electrical equipment from overvoltage, undervoltage, and overcurrent conditions in a 230V AC electrical system. It acts as a circuit breaker, automatically disconnecting the power supply when voltage or current levels exceed or fall below pre-set thresholds, thus preventing damage to connected appliances. Key Features and Functions: Overvoltage Protection: The device will cut off the power if the voltage exceeds a set limit, preventing damage from surges. Undervoltage Protection: It will also disconnect the power if the voltage drops below a specified level, protecting sensitive equipment from low voltage conditions. Overcurrent Protection: The device will trip if the current exceeds the rated 63A, preventing damage from short circuits or overloads. Adjustable Settings: Many models allow users to customize the overvoltage, undervoltage, and overcurrent trip points, as well as the delay time before reconnecting power. Automatic Reconnection: After a fault is cleared, the device can automatically reconnect the power supply, eliminating the need for manual reset. DIN Rail Mounting: Most models are designed for DIN rail installation, making them easy to integrate into standard electrical panels. Digital Display: Some models feature a digital display that shows real-time voltage and current readings, as well as the status of the protection functions. Versatile Applications: These protectors are suitable for a wide range of applications, including residential, commercial, and industrial electrical systems. In essence, the AC guard 63A-230V is a crucial safety device that helps protect your valuable electrical equipment from common power-related issues, ensuring
