1. Construction and Feature
In a device, the contactor is converted between normally open or normally closed by positive/anti pulse voltage exciting the coil instead of long-term power supply and the contactor of relay keeps closed just withthe magnetic power of permanent magnetic steel. Over the electromagnetic replay, permanent magneticrelay takes the advantage of less consumption in energy and material, stable performance, smaller size, larger carrying capability, and electromagnetic driving mechanism consumption current is approximately 30mA, while the one of permanent magnetic mechanism is approximately 5mA.
Automatic reset function: As the break of neutral line and the potential offset lead to overload or under voltage of single-phase line, the protector automatically trip and cut-off the power supply and automatically switch to the load source after e-minute-delay later after the electric network is recovered to normal value so as to protect electrical equipment from over/under voltage.
The case is in fire-retardent material, concise and lively outline, modular design, reail mounting. Bi-color LED display work state: Green(normal), red(faulty)
2. Application
When the city power voltage exceeds protector action voltage, the protector will cut off the power quickly and reliably so as to protect electrical equipment and people safety. When the city power voltage recovers normal value, the protector will cut on the power automatically without manual operation, Four LED on the panel can indicate the working status of protector. The protection function starts and cut off the power when the first indicator is red. The power is supplied normally when the second indicator light is green. The power is supplied under-voltage when the third indicator light is red. The protector is in waiting time status when the forth indicatoris yellow.

FAQ:
Q 1. What's the payment term?
A. We accept TT, 30% deposit and 70% balance agaisnt copy of BL
Q 2. How's the delivery time?
A. Usually it will take about 25 days for production
Q 3. Tell me the standard of package?
A. Normally are cartons, but also can packed into PLATES for more safe.
Q 4. What kind of material of circuit breaker?
A. We have two types, one copper coil with silver point and the other is brass coil with copper point. It depends on your requirement. In fact, those two have no difference if normal work well. Only except the electrical life. Copper and silver is better and also higer price.
Q 5. Could you offer Form A or C/O?
A. It totally not a problem. We can prepare relative documents to forgin affairs office or other office to apply for this certificate.
Q 6. Would you accept to use our logo?
A. If you have good quantity, it absolute no problem to do OEM.
Q 7. We want to know month capacity.
A. 360000pcs/month
Q 8. Where is your market?
A. Our products are popular in UK, Iran, Pakistan, India, Dubai, Zambia and so on. Some of them are our regular customers and some of them are developing. We hope you can join us and make mutural benifit from our cooperation.
Q9. What kind of certificate you have?
A. Our company already achieve ISO, and for products, we have CE
