Product Description

Product Description
Floor-type boundary switch integrated prepaid metering device is a product that changes the high-voltage metering, switch, and control box on the column into a cabinet-type structure. Combination, the box is made of stainless steel or iron plate spray material. This product is easy to install in structure, beautiful in appearance, the high-voltage part is completely isolated from the low-voltage meter room, and the high-voltage room cannot be opened when the equipment is powered on. The product occupies a small area and is a perfect combination product for living areas, industrial and mining enterprises and box-type transformers. Personnel can directly open the door to view the bottom of the watch and operate the switch on the spot. The transformer is vacuum cast with fully enclosed epoxy resin, thus eliminating the problem of aging. The demarcation switch part adopts vacuum switch with zero-sequence and protection current transformers, and realizes zero-sequence, over-current and quick-break protection with intelligent controller, which can realize automatic removal of single-phase ground fault and automatic isolation of phase-to-phase short-circuit fault. Ensure electricity safety for non-faulty users. This product has the FTU function to realize the switch remote control opening and closing, and also has the GPRS remote control function.

Product technical parameters and external dimensions





Product structure features 
1. Vacuum arc extinguishing, strong breaking capacity, long electrical life and 10,000 mechanical life;
2. Simple structure, maintenance-free, long maintenance period;
3. Good insulation performance and strong anti-pollution ability;
4. It can be equipped with spring or electromagnetic operating mechanism, with reliable mechanical performance and frequent operation; no fire and explosion hazard;
5. Built-in current transformer, the lecturer's precision reaches 0.2, which can realize three-phase interactive protection;
6. With condensation controller, it can keep the circuit breaker running reliably under certain temperature and humidity.



Environment condition

1. Ambient air temperature: -5~+40 and the average temperature should not exceed +35 in 24h.
2. Install and use indoors. Altitude above sea level for operation site should not exceed 2000M.
3. Relative humidity should not exceed 50% at max temperature +40. Higher relative humidity is allowed at lower temperature. Ex. 90% at +20. But in view of the temperature change, it is possible that moderate dews will produce casually.
4. Installation gradient not exceed 5.
5. Install in the places without fierce vibration and shock and the sites insufficient to erode the electrical components.
6. Any specific requirement, consult with manufactory.
