DZ47LEGQ-63 leakage with over-voltage protection miniature circuit breaker (hereinafter referred to as the over and under voltage circuit breaker), household over and under voltage, leakage circuit breaker. Our company is a new development of a new type of circuit breaker, the main functions of the undervoltage protection, overvoltage protection, leakage protection, instantaneous protection and delay protection five protection as a whole, this product has the advantages of small volume, convenient installation, stable performance, low price, good qualitycharacteristics, by consumers and users liked.
Product features
Small size: DZ47LE volume as large, size of 63*92*75 (under voltage size 2 pole breaker and leakage +).
Convenient installation: modular rail mounting.
Excellent performance: undervoltage protection, overvoltage protection, leakage protection, instantaneousprotection and delay protection five protection as a whole,
Undervoltage protection: 170V ± 5% reliable tripping off air switch.
Overvoltage protection: 280V ± 5% reliable tripping off air switch.
Leakage protection: leakage (30mA, effectively release Ma is 22~26mA).
Instantaneous protection: when the line short-circuit conditions, air switch tripping.
Delay protection: when the line is over the rated current, air switch (circuit breaker) will be based on the overcurrent tripping, 1.05 times 1 hours without action, 2 hours of action (action for the circuit breaker automatically trip).
Range of use
Using a range of DZ47 air switch
DZ47-63 series high section miniature circuit breaker (air switch), has advantages of advanced structure, reliable performance, high breaking capacity, beautiful appearance and small features, shell and the insulating parts withgood insulation, impact resistance, high flame retardant materials. Applicable to AC 50HZ or 60HZ, rated voltage400V, rated current is 63A the following places. Mainly used in office buildings, residential buildings and similarlighting, power distribution line protection and equipment overload, short circuit, also can be in normal circumstances, as the transfer line is not frequent use, the product meets the requirements of IEC60898 and GB10963 standard.
The use of DZ47LE leakage switch
DZ47LE-63 residual current leakage circuit breaker (air switch) for AC 50HZ, 230V single-phase, three-phase400V circuit, when someone gets an electric shock or circuit leakage current exceeds the set value, the leakage circuit breaker can automatically cut off the power supply in the 0.1s, to protect the personal safety and preventaccidents caused by leakage current, but also as a overload and short circuit protection circuit with, as well as in the normal condition as the line is not frequent conversion in. This product complies with IEC61009-1 and GB16917.1 standards.
Over and under voltage range
Over and under voltage is designed for the auxiliary function components supporting the design of DZ47 seriescircuit breaker, overvoltage, undervoltage, by providing overvoltage and undervoltage detection on the power supply, to control the circuit breaker on-off, cut the distribution system circuit and detection circuit breakers. The use of DZ47 can and DZ47LE series circuit breakers.
Over and under voltage protection performance
The input power supply over-voltage and under voltage caused harm to the switching power supply, mainly in thedevice for voltage and current stress and damage beyond the range of normal use, at the same time due toelectrical performance index is damaged and can not meet the requirements. The upper and lower bounds on theinput power should be restricted, the overvoltage, undervoltage protection in order to improve the reliability and safety of power supply. Temperature is the most important factor influencing the reliability of power supplyequipment. According to the data analysis shows that, electronic component temperature rise every 2 ℃, 10% drop reliability, temperature 50 ℃ working life only the temperature 25 ℃ 1/6, in order to avoid power deviceoverheating damage, in switching power supply also need to set the overheat protection circuit
Summary: currently on the market too owed a lot, pressure protection products a superb collection of beautiful things, but the household with leakage of over-voltage product does not see more, some products are linked toan auxiliary products in the circuit breaker beside, achieve undervoltage function, but can not realize the leakage protection function, thus lost the protection function of the real meaning is the people, and the price of a productwith a leakage protection and over-voltage protection function is very expensive, are hundreds of yuan, and I developed the over and under voltage, leakage protection circuit breaker price only half of their price, to achieve the true sense of the over-voltage protection circuit breaker affordable. Leakage.
