DZ47 (C45-miniature circuit breaker instructions
A use.
DZ47-63 (C45-63) miniature circuit breaker < http://www./products.asp? Clsid = 747 > (hereinafter referred to as "circuit breakers" http://www. >) is mainly used for communication frequency 50 Hz / 60 Hz, to 400 V rated voltage, electric current to 63 A electrical wiring and equipment of the overload and short circuit protection, can be used as A line not frequent changeover with.
At present our company production of small circuit breaker highest current can reach 125 A, 63 A above the current arrangement has 80 A, 100 A, 125 A.
Small circuit breaker and divided into C and D type, general family expenses for C circuit breaker http://www./products.asp? < Clsid = 747 >, the power system in use in the circuit breaker < http://www./products.asp? type D Clsid = 747 >.
The product model and meaning

Product categories
According to the extreme number classification are:
Unipolar (1 P) circuit breakers
2 extremely (2 P) circuit breakers
Level 3 (3 P) circuit breakers
Four very (4 P) circuit breakers
According to the rated current points:
6 A, A, A, 10 16 20 A, 25 A, and A, 40 A, 50 A, 63 A, 80 A, 100 A, 125 A.
Rated voltage unipolar for 230 V / 400 V, 2 extremely, level 3, level 4 for 400 V.
According to the instantaneous tripping current points C and D type.
Normal conditions of use
Ambient air temperature is not less than 5 degrees, not more than + 40 degrees, the average day not more than + 35 degrees.
Installation site altitude not more than 2000 meters.
Air relative humidity, at the highest temperature + 40 degrees to no more than 50%, in lower temperature can have high humidity, such as the wet month average temperature not more than + 25 degrees, month average relative temperature not more than 90%, and allow due to temperature changes in product surface send gel.
Use the level of pollution circuit breaker site level to level 2.
The circuit breaker TH35-7.5 steel installation guide installation.
Circuit breaker http://www./products.asp? < Clsid = 721 > installation category II and III is usually.
According to normal work position installed circuit breaker, mounting surface and the rake of vertical plane is no more than the plus or minus 5 degrees.
Circuit breaker wiring method, with the screw press the wiring.
Circuit breaker with isolation function.
Technical data
A current tripping characteristics
Circuit breaker in the benchmark environment temperature 30 to 35 degrees of under the flow tripping characteristics should be in accordance with table 1.
This product conforms to the standard GB14048.2 / GB10963.1.
Rated short circuit hige capacity: Ics = Icn = 4500 A (is equal to or greater than 40 A) / 3000 A (less than or equal to 50 A).
Remaining short circuit connected points off ability: Im = 2000 A
A table over current tripping characteristics
Rated current In (A) start state inspection current A stipulated time expected results test environment temperature t
More than 63 A cold state In 1.13 t quartile 1 h 30 ℃ ~ not tripping 35 ℃
More than 63 A cold state In 1.45 t quartile 1 h 30 ℃ ~ tripping 35 ℃
A cold state than 32 In 2.55 t quartile 1 h 30 ℃ ~ tripping 35 ℃
> and the cold 2.55 In 1 s < t < 120 30 ℃ ~ s tripping 35 ℃
More than 63 A cold state 5 In t quartile 0.1 s 30 ℃ ~ not tripping 35 ℃
More than 63 A cold state 10 In t quartile 0.1 s 30 ℃ ~ tripping 35 ℃
6. Structure characteristics and working principle
This circuit breaker have contacts, arcing system, electromagnetic system and tripping institutions and operating mechanism and composition, the electromagnetic system USES JingMiXing and resistance type double metal materials, the contactor adopts silver cadmium oxide contacts, and also choose the enhance arc plastic resistance new materials, guarantee product performance.
The working principle:
In the normal work of the circuit breaker circumstances press the operating mechanism, make the power is connected, this time the tripping institutions atresia, contacts do not move, when the current is too large, the electromagnetic system optic-fiber deformation, and promote the lock, make the iron core is attracted, contacts in the release under the action of spring and disconnected, complete the circuit breaker protection break points.
Seven. Appearance and installation size
The appearance of the circuit breaker and installation dimensions, see table 2 and figure 3

Shape dimension instructions figure (figure 3)

Installation and adjustment
Circuit breaker before the installation, should notice the following matters:
Check the breaker, confirm intact, and flexible motion;
Check the circuit breaker sign is and the use of normal working condition accord with.
Circuit breaker installation should be paid attention to when the wiring logo. Properly installed.
Rated current cannot adjust themselves, and do not need to maintenance.
Installation and removal methods:
Will RuGui place at the installation guide circuit breaker bottom, make the circuit breaker http://www./products.asp? < Clsid = 721 > along the direction of arrow upward push, and assured by the arrow will sunken place pushed to the installation guide rail, close to let go.
And the installation process instead, make along the direction of arrow top up circuit breaker, make the circuit breaker against direction, can remove.
The use and maintenance
Circuit breaker (including packing products) in the transportation and keeping, shall not be rain hit, the product should be placed in no rain and snow, the air circulation into the environment, on average relative humidity is not more than 90% (in 20 ± 5 ℃), air temperature is not higher than + 40 ℃ and not less than 25 ℃-the Treasury

  
Miniature circuit breakers is also known as miniature circuit breakers (circuit breaker) hereinafter referred to, which is characterized by a high breaking capacity, advanced structure, reliable performance, compact appearance, casing and insulation parts using performance insulation, impact resistance, resistance toThe high temperature material.Line is not suitable for AC 50HZ or 60HZ, rated voltage 400V, rated current for 3 ~ 125A places, mainly used for office, residential and architectural lighting, power distribution lines and equipment overload, short circuit protection, also can be used asfrequent use of the conversion, the product complies with the requirements of IEC60898 and GB10963 standard.
