Over Voltage Drain Circuit Breaker DZ47LEGQ-63 / 2P

DZ47LEGQ-63 Leakage beltOvervoltage protection of small circuit breakersHereinafter referred to as undervoltage circuit breakers), household over-voltage leakage circuit breakers. Is a new development of the company's new circuit breaker, the main function of undervoltage protection, overvoltage protection, leakage protection, instantaneous protection and delay protection of five protection as one, this product has a small size, easy installation, performance Stable, low prices, good quality and other characteristics, by consumers and users love.

Small size: DZ47LE as large as the size of the size of 63 * 92 * 75 (2-pole open leakage + over-voltage dimensions).

Easy installation: Modular rail mounting.

Excellent performance: undervoltage protection, overvoltage protection, leakage protection, instantaneous protection and delay protection of the five protection as one,

Undervoltage protection: 170V ± 5% reliable trip breaking air switch.

Overvoltage protection: 280V ± 5% reliable trip breaking air switch.

Leakage protection: leakage 30mA, (effective trip mA for 22 ~ 26mA).

Instantaneous protection: When the line is short-circuited, the air switch is automatically tripped.

Delay protection: When the line appears more than the rated current, the air switch (circuit breaker) will be based on more than the current trip, 1.05 times 1 hour without action, 2 hours action (action for the circuit breaker automatically trip).

Use range
DZ47 air switchThe scope of use
DZ47-63 series of high-segment small circuit breaker (air switch), with advanced structure, reliable performance, high breaking capacity, the appearance of small and so on, shell and insulation parts with good insulation, impact resistance, high flame retardant materials to make. Applicable to AC 50HZ or 60HZ, rated voltage below 400V, rated current of 63A below the place. Mainly used for office buildings, residential and similar buildings lighting, distribution lines and equipment overload, short circuit protection, but also under normal circumstances, as the line is not frequent conversion purposes, the product in line with IEC60898 and GB10963 and other standards The

DZ47LE leakage switchThe scope of use

DZ47LE-63 residual current leakage circuit breaker (air switch) for AC 50HZ, single-phase 230V, three-phase 400V line, when someone electric shock or circuit leakage current exceeds the specified value, the leakage circuit breaker can be automatically cut off within 0.1s Power supply, protection of personal safety and the prevention of equipment due to leakage caused by leakage of the accident can also be used as a protection circuit overload short circuit, and under normal circumstances as a frequent conversion of the line. This product meets the requirements of IEC61009-1 and GB16917.1 standards.


Overvoltage use range

Overpressure is designed for DZ47 series circuit breakers supporting the design of auxiliary function components, through the power supply overvoltage, undervoltage, overvoltage detection, to control the circuit breaker on and off, breaking the distribution system circuit or detect circuit breaker signal The And DZ47 and DZ47LE and other series of circuit breakers supporting the use of.


Overvoltage protection performance

The power supply overvoltage and undervoltage on the switching power supply caused by the hazards, mainly in the device due to withstand the voltage and current stress beyond the scope of normal use and damage, while the electrical performance indicators are destroyed and can not meet the requirements. Therefore, the upper and lower limits of the input power supply should be limited, for which the use of overvoltage, undervoltage protection to improve the reliability and safety of power. Temperature is the most important factor affecting the reliability of power supplies. According to the relevant data analysis shows that the electronic components of the temperature rise of 2 ℃, the reliability decreased by 10%, the temperature rise of 50 ℃ when the working life is only 1/6 of the temperature rise of 25 ℃, in order to avoid damage to the power device overheating, Switching power supply also need to set the overheat protection circuit


Summary: the current market over-voltage protection products are many, dazzling, but the home with leakage of over-voltage products are rare, and some products are in the circuit breaker next to an auxiliary product, to achieve undervoltage function, But can not achieve leakage protection function, so that the real meaning of the loss of personal protection, and with leakage protection and over-voltage protection of the product price is very expensive, are hundreds of dollars, and I developed thisOver - voltage leakage protection circuit breakerThe price is only half of their price, the real sense of the people to buy from the leakage of over-voltage protection circuit breakers.
