Fiberglass SMC meter box is made by craft of moulding SMC unsaturated polyester resin, Fiberglass reinforced plastics.
Its specialty has solved the problem of wooden meter box, steel meter box and plastic meter box, such as easy to aging, rust, poor insulation performance, poor cold resistance, poor fire resistance and short service life.
SMC meter box has good quality of high strength,Lightweight,anti-corrosion,installation fastness,rain proof,preventing electric energy stealing.anti-rust,easy to operate and so on.
SMC meter box can be installed on the pole, hanged on the wall or in the wal.Besides all kinds of mechanical meter or electric meter as well as user’s switch and leakage protector can be installed inside.
Residential buildings: Meter boxes are usually installed on the exterior walls of residential buildings, garages, or cable Wells for the installation of meters and circuit breakers. They ensure accurate metering and safe management of household electricity.
Commercial buildings: In commercial buildings such as office buildings, shops or restaurants, meter boxes are used for centralized installation of meters and related electrical equipment. They support the monitoring and management of power consumption in a business environment.
Industrial facilities: Industrial sites require high-power power supply, so meter boxes play an important role in these facilities, able to accommodate multiple meters and complex power control equipment to meet the needs of industrial electricity.
Public facilities: In public facilities such as schools, hospitals and government institutions, meter boxes are used to ensure the power supply and safety of these important facilities, supporting large-scale electricity metering and management.
Construction sites: On construction sites, meter boxes are used for temporary power supply, ensuring that the power needs of construction equipment and tools are met, while protecting the power equipment from the construction environment.
Residential area: In the distribution room or cable well of the residential area, the electricity meter box is centralized to install the electricity meter of multiple households, which is convenient for the management and maintenance of the power company.
Commercial area: In a commercial area or shopping center, the meter box can be used to measure the electricity consumption of different shops in different areas to help with electricity distribution and cost accounting.
Plastic-case circuit breaker and air switch are two different types of electrical protection equipment, and they have obvious differences in design, function and application scenarios.
Design differences: Plastic-case circuit breakers use plastic insulators as the housing of the device to isolate conductors and ground metal parts. This design makes the circuit breaker suitable for a variety of environmental conditions, including a wide temperature range and altitude. In contrast, air switches (also known as miniature circuit breakers or miniature circuit breakers) have a simple design, a relatively small current, and are usually used more widely in home lines.
Functional differences: Plastic-case circuit breakers usually contain thermal magnetic trip units, and large-size plastic-case circuit breakers will be equipped with solid-state trip sensors. The trip unit of plastic-case circuit breaker is divided into thermal magnetic trip and electronic trip, which is suitable for large current and is mostly used in industrial distribution cabinets and substations. The air switch is mainly used for overload short-circuit protection, and the current is relatively small, generally not more than 63A, which is suitable for household common circuits.
Difference in application scenarios: Because it can pass a large current (not more than 600A), plastic-case circuit breakers are usually used as low-voltage main switches, which are more common in industrial distribution and substation. The air switch, due to its smaller current carrying capacity, is more suitable for home circuits to provide basic overload and short circuit protection.
In summary, the main difference between plastic-case circuit breakers and air switches is their design, function and application scenarios. Plastic-case circuit breakers are more complex in design and can handle larger currents for industrial and commercial applications. The air switch design is simple, the current is small, mainly used in home circuits.
