Product Details

1、 Scope of application

The DZ47-63 miniature circuit breaker is mainly suitable for circuits with AC 50/60Hz, rated working voltage of 230V/400V and below, and rated current up to 63A. This circuit breaker is mainly used for overload and short circuit protection of electrical lines and equipment in modern buildings, and is also suitable for infrequent operation and isolation of lines. structural characteristicsThe electric scooter circuit breaker consists of a plastic casing, an operating mechanism, a contact arc extinguishing system, a trip mechanism, etc. The shell is made of high flame retardant and high-strength special plastic, with strong impact resistance and light weight. The components of the electric scooter circuit breaker operating mechanism are made of high-strength plastic products, which ensure sensitivity and reliability while obtaining the lowest moment of inertia, making the time from the start of a short circuit fault to the action of the trip mechanism very short. The trip mechanism consists of two parts: a bimetallic overload inverse time trip mechanism and a short-circuit instantaneous electromagnetic mechanism. The contact arc extinguishing system adopts special arc angles and aisle extinguishing chambers, and has significant current limiting characteristics. This product is mainly used for overload and short circuit protection of lighting, distribution lines, and equipment in office buildings, residential buildings, and similar structures. It can also be used for infrequent conversion of lines under normal conditions. It meets the requirements of standards such as IEC60898 and GB10963.1. Has passed the national CCC certification and CE certification.
Type C is used for home power distribution protection; D-type is used for motor protection

3、 Normal working conditions

The upper limit of the surrounding air temperature shall not exceed plus forty degrees Celsius; The lower limit generally does not exceed minus five degrees Celsius. Used under conditions above positive 40 degrees Celsius or below negative 5 degrees Celsius
The altitude of the installation site generally does not exceed two thousand meters.
The air is clean, and at a maximum temperature of 40 degrees Celsius, the relative humidity of the air should not exceed 50%.
Higher relative humidity is allowed after class at lower temperatures, for example, at a temperature of 20 degrees Celsius, the relative humidity can reach 90%.
It should be noted that due to temperature changes, moderate condensation may occasionally occur, and appropriate measures should be taken (such as drainage holes).
The circuit breaker of the electric scooter should be installed vertically, with a tilt angle of no more than 5% from the vertical plane.
A place without significant shaking or impact vibration.
If installed inside a closed protective enclosure and multiple units are installed closely together, the capacity reduction factor should be selected from 0.7 to 0.8. For metal protective enclosures, a high value can be used, and for all plastic protective enclosures, a low value can be used!
