First, the scope

DZ47 MCB is mainly used in AC 50/60Hz, rated working voltage of 230V/400V and below, rated current up to 63A of the circuit, the circuit breaker is mainly used in electrical circuits of modern buildings and overload, short circuit protection device, also applicable to infrequent line operation and isolation. Structure DZ47 MCB made of plastic shell, operating mechanism, contact interrupter system, off buckle mechanism and other components. Shell using a special plastic high flame retardant, high strength, high impact resistance, light weight. Part breaker operating mechanism employs high-strength plastic products, to ensure that sensitive and reliable at the same time get the lowest moment of inertia, so that short-circuit fault from the beginning to the tripping mechanism operation time is very short. Tripping mechanism bimetallic overload by the inverse time tripping mechanism and short-circuit instantaneous electromagnetic bodies of two parts. Contact interrupter system is the use of special guide arc angle and aisle destroy chamber, and has a significant limiting features. Overload, short circuit protection is mainly used in office buildings, residential buildings and similar lighting, power distribution lines and equipment, but also under normal circumstances, as infrequent line conversion purposes, the product complies with IEC60898 and GB10963.1 etc. standards. Tessie production DZ47 MCB ( B-type battery car breaker ) has been the national CCC certification and CE certification.
B-type protection for car battery; C type used in home distribution protection; D type for motor protection

Second, model and specification

Third, the normal working conditions

maximum ambient air temperature does not exceed the positive forty degrees Celsius; the lower limit of not more than negative five degrees Celsius. Use should contact Tessie electrical technology department at temperatures above or below the negative positive forty five degrees Celsius conditions.
The installation site altitude is generally not more than two thousand meters high.
The air is clean, and the maximum temperature being forty degrees Celsius, the relative humidity of the air shall not exceed 50 percent.
Class at a lower temperature allows greater relative humidity, for example n-twenty degrees Celsius, relative humidity may reach 90 percent.
It should be noted, due to temperature changes, may occasionally produce moderate condensation, and you should take appropriate measures (eg drainage holes).
Breaker mounted vertically, and the vertical gradient of not more than five percent.
No significant shake and shock vibration.
If installed in a closed protective housing, and should be installed in close proximity to multiple derating, derating factor of 0.7 to 0.8 Optionally, the metal protective shell can be a high value on the plastic protective shell, you can use low !

VI Notes

A grade quality: copper fittings, fire-retardant shell, silver point
Grade B Quality: brass fittings, ordinary plastic, alloy point
C grade quality: iron fittings, ordinary plastic, copper points
For A-grade quality, made it clear that the quality of the case shall be QQ or telephone inside, can also be customized according to customer requirements for production quality (demand reach certain circumstances), C-class quality is poor, very basically our production, because C quality is not high, for producers Please also contact!
DZ47 miniature circuit breakers General quoted by market generic B-quality quotes, quotations normally excluding taxes, For a VAT invoice, plus 10% of the price points
Another: Division I undertake a large-scale enterprise outsourcing the production process. Profit is very low due to the small circuit breakers, is willing to cooperate in the demand for larger enterprises, has 12 years of Division I experience, absolute guarantee of safety and quality!
