The Shell is Sturdy and Shock resistant

The casing of the meter is crafted from high strength engineering plastic, undergoing fine surface processing to achieve a smooth, burr free finish with a sleek, modern appearance. It boasts excellent shockproof and compression resistant performance, capable of withstanding mechanical vibrations and slight impacts common in industrial sites without structural damage or performance degradation. Additionally, the material’s acid and alkali resistance ensures a long service life in various complex working environments.

Flame Retardant ABS Material

Adopting high grade flame retardant ABS engineering plastic, the meter’s casing meets stringent safety standards. Flame retardant materials can effectively inhibit combustion and prevent the spread of fire caused by high temperatures generated by instrument faults such as short circuits and overloads. This design fundamentally eliminates fire safety hazards, providing a reliable safety guarantee for the entire power system and making it suitable for use in fire prone industrial and commercial settings.

High definition 178° Full Field of View

Equipped with a high definition digital large screen LED display, this meter features large, bright characters for unparalleled clarity. The screen supports a 178° full viewing angle—readable from above, below, or any side with no blind spots—ensuring operators can read critical data quickly and accurately from any position. The instrument’s strong anti interference capability ensures stable measurement and display even in the most complex electromagnetic environments.

Multiple Overload Alarms for Safe Electricity Use

The wiring is simple, enabling quick installation and use; the terminals are made of copper, which has strong conductivity, resulting in faster output and less loss. The high current terminal block guards the safety of electric current, while multiple overload alarm functions provide real time warnings for abnormal power conditions, effectively preventing equipment damage and ensuring safe electricity use.

Can be Used with DIN rail

It can be installed using the universal DIN35mm standard guide rail, unlocking more usage scenarios. The snap on installation buckle allows for tool free mounting and dismounting, making it convenient for installation, maintenance, and replacement in distribution cabinets and industrial control panels.
