Note 1: the lower limit value is -10 or -25 C C working conditions, in order to factory users must be given;

Note 2: the upper limit or lower limit value of more than +40 DEG C below -25 DEG C working conditions, the user should consult with the manufacturer.

2), the installation site altitude not exceeding 2000m;

3), relative humidity of the atmosphere in the surrounding air temperature of +40 is less than 50%, allowing a higher relative humidity at lower temperatures, for example at +20 DEG C to 90%, take appropriate measures due to temperature change should occasionally produce;

4), pollution level: 2;

5), installation categories: Class II and class iii;

6), field installation site in any direction shall not exceed 5 times the earth's magnetic field;

7), usually installed in a vertical direction to allow any difference of 2 degrees;

8), installation should be no significant impact and vibration.

Applicable scope

Miniature circuit breaker with advanced structure, reliable performance, high breaking capacity, compact appearance and other characteristics, mainly used in AC 50HZ or 60HZ, rated voltage 400V, rated current is 63A the following places. For office buildings, residential buildings and similar lighting, power distribution lines and equipment overload and short circuit protection, but also as a line without frequent on-off operation and conversion in. Mainly used for industrial, commercial, and residential high-rise and other places.

Miniature circuit breaker is composed of the following components:

The 1 section contact connection. It is composed of the fixed contactor and the movable contactor to form.

2 by a metal cylinder or a device consisting of a dielectric cylinder, the installation can be divided into contact connection broken and extinguishing equipment and transmission device.

3 drive transmission device contact.

4 arc extinguishing equipment.

The commonly used small circuit breaker circuit is to separate small circuit breaker moving contact and fixed contact by mechanical means. The closing is used instead of mechanical movement of the moving contact and the fixed contact is closed. In the switch on and off load circuit operation, fixed contact and moving contact can be generated between arc. Arc breaking process produces much more serious than the closing process. When the breaking current is large, especially when breaking short circuit, open circuit arc, often very difficult.

1), rated short-circuit breaking capacity is high, some current rating can reach more than 10KA.

2), double junction function, can be conveniently connected to standard bus and soft wire.

3), with finger protection combination terminal, more security.

4), energy storage mechanism, rapid contact closure, overcome the adverse effect caused by human operation handle speed, improve the service life of the product.

5), a variety of optional accessories, and modular, flexible assembly, installation is very convenient to users.

6), shell and some functional parts are made of imported high flame retardant, high temperature, impact resistant plastic.

7), the limiting factor is high, performance price ratio.
