Intelligent Voltage Protection: AC 110V 220V/DC within 80-300V range, with adjustable 1-40A overcurrent protection. Automatically cuts off power in case of overvoltage or undervoltage to protect your appliances and home safety.
Multiple adjustable protection functions: The overcurrent protection can be adjusted from 1 to 63A, and the delay time can be adjusted from 1 to 900 seconds, meeting the startup requirements of different devices. The overvoltage protection can be adjusted from 130V to 300V, and the undervoltage protection can be adjusted from 80V to 210V, precisely setting the protection threshold. The digital display screen shows the voltage and current readings in real time, facilitating precise monitoring and parameter adjustment.
Wide range of applications: highly suitable for whole-house protection, campers, solar systems and industrial equipment. Protects sensitive electronic devices from voltage fluctuations and surges.
Easy-to-install DIN rail: The standard 35mm DIN rail design is suitable for quick installation in electrical panels. The compact 2-pole design saves space while providing comprehensive protection.
Product Specifications: Includes 1 intelligent circuit breakers. It is equipped with a flame-retardant thermosetting plastic casing, which is resistant to high temperatures and fireproof, ensuring safety and compliance with electrical safety standards. It is suitable for professional-level protection in both residential and commercial settings, providing reliable electrical safety assurance.
