KXQV-63 serious intelligent self recovery over voltage protection device

Application:

Low-voltage distribution system TN-CS,TN-S,TT earth connect type, due to neutral line fault caused low-voltage distribution system electric potential deflection, too much electric potential deflection will not only make fire disaster burn up single phase electric devices, even endanger personal safety. Mainly used to residence individual box incoming wire or protecting single phase electric apparatus distribution circuit. Overvoltage, undervoltage is unexpected, it's not convenient and unsafe for resident with old and sick family members if adopt handle restart, that's why each resident should match self recovery overvoltage and undervoltage protection device.

Apply to user circuit of single phase AC voltage 220V, frequency 50Hz, rated current equal or lower than 63A.

Function:

Overvoltage/undervoltage protection and self recover, automatic ON/OFF circuit breaker.

Working principle:

KXQV-63 series intelligent self recovery over voltage protection device is a new type household electric protection device. Control Circuit adopt imported component to assemble, product according modularization standard to produce, excellent and reliable performance. Can work normally in abnormal voltage condition. Protection device can cut off circuit reliability and rapidly when power supply voltage exceed or lower than protection device operation voltage, so that can protect apparatus and personal safety. Protection device can connect power supply automatic, recover power supply when power supply voltage turn to normal, all those functions can automatic operate, no need personal operate.

Model No. and meaning: 

Product characteristic:

1.         Protection device can cut off circuit automatically when voltage lower than setting undervoltage protection parameter; Protection device can connect circuit automatically when voltage higher than setting undervoltage protection parameter;

2.         Protection device can cut off circuit automatically when voltage higher than setting overvoltage protection parameter; Protection device can connect circuit automatically when voltage lower than setting overvoltage protection parameter;

3.         This protection device in automatic connecting status when the working pressure between Uoe-Uvo.

4.         Modularization design, 35mm standard rail installation

5.         Protection device won't make malfunction when circuit with instantaneous or temporary overvoltage

6.         Protection device won't be destroyed when circuit fault with maximum voltage

7.         Impact resistant voltage:4Kv(according to III type apparatus safety standard)

Bimetal:   Actually, it contains three metals iron, copper, cadmium, galvanized. Three metals with different coefficients of thermal expansion, bending cause thermal Pick reflect and making the breaker disconnect. This is the most import parts of the circuit breaker.  The Bimetal is the use of different materials under different breaker amperage.

Coil:  It's the important parts for the reaction of the Magnetic Trip. It's always 9 ring. As a matter of fact, the number of Coil with Different Amperage.For example, 1A reaches over 100 ring, and 63A is used to 56 ring. The Diameter Thickness is also different for Amperage.

Action Contactor(Sliver Point): It's the main point for the Reaction of Trip. Under normal conditions, keeping closed. When overload and short circuit, It will be breaking.

Arc Chute: Playing a role in destroying the arc. Generally tend to produce a large number of Moving and Static Contactor from the contactor, arc, even emerge spark.
