Two inlet,multi-outlet connection terminal block for metering box
Along with the increase of electricity users and centralized installation management of metering device, the company developed single-phase multi-circuit output terminal block to meet the ever-changing market needs. It is the new generation of multifunctional products launched on the market by the company.
The products have passed the tests carried out by relevant power departments, are in accordance with national standard GB14048 and safety requirements in utilizing electric energy, the products are popularized and used by more and more electricity management units.
Featured with small volume, large current carrying capacity, many households use, high withstanding voltage, compact structure, convenient installation, nice appearance, etc., this product has many superior properties such as flame retardant, no water absorption, wetness prevention, perfect insulation, anti aging, etc..
Owning to transparent cover plate, it has perfect visualization; the outgoing wire is enclosed type, so it is very safe and reliable.
This product supports metering of multi-meter-position, it not only avoids the defect of service-entrance wire entering into bare copper bar directly, inconvenient overhaul, but also saves the mounting space, cuts down the cost of metering box. It can be divided into two-inlet four-outlet, six-outlet, eight-outlet, ten-outlet…forty-outlet, etc.
