Used for real-time monitoring of residual current, voltage, current and other parameters of the distribution system, achieving accurate alarm and electrical fire protection for faults such as leakage and overload, and ensuring electrical safety.


Advantages:
·Accurate monitoring: Using high-precision sampling chips, the residual current measurement accuracy can reach ± 0.5% or ± 1%, far higher than ordinary pointer instruments, and the identification of fire hazards is more sensitive.
·Space saving guide rail installation: The standard 35mm guide rail design is directly embedded into the distribution cabinet/distribution box, without the need for additional cabinet modifications, making installation convenient and saving a lot of panel space.
·Strong anti-interference ability: Built in EMC electromagnetic filtering circuit, strictly resisting strong electromagnetic interference in industrial sites, stable data acquisition without jumping, and reliable long-term operation.
·Remote monitoring automation: Supports RS485 communication interface (Modbus RTU protocol), seamlessly integrates with building automation and SCADA systems, and achieves remote unmanned monitoring.
·Multiple alarm mechanism: Supports sound and light alarms, contact output alarms, and can be linked to equipment such as fans and pumps. When a fault occurs, it automatically cuts off the dangerous circuit to prevent it from happening.
·Full range coverage adaptation: Supports 50Hz/60Hz multi band power grids, with freely adjustable voltage and current ranges, compatible with various complex electrical environments such as industry and commerce.
·Easy self check and reset: Equipped with a TEST test button and RESET reset button, it can quickly perform device self check and fault reset, with high maintenance efficiency and reduced downtime losses.
·High protection and durability: The shell is made of flame-retardant PC material, with high protection level, earthquake and humidity resistance, suitable for harsh industrial sites such as high temperature and high humidity, and a service life of up to 5-8 years.
