Miniature circuit breaker product price introduction, working characteristics of miniature circuit breaker

The miniature circuit breaker, also known as the miniature circuit breaker, is suitable for AC 50/60Hz rated voltage 230/400V, rated current to 63A line overload and short circuit protection. Therefore, the miniature circuit breaker is very practical in our life, and then Xiaobian will tell you about the knowledge of miniature circuit breakers.

First, the price of small circuit breaker products:

Miniature Circuit Breaker (English name: Miniature Circuit Breaker), also known as Micro Circuit Breaker, is suitable for AC 50/60Hz rated voltage 230/400V, rated current to 63A line overload and short circuit protection, also in Under normal circumstances, it is used as an infrequent operation conversion of the line.

Miniature circuit breakers are mainly used in various places such as industrial, commercial, high-rise and residential buildings. Here are some prices for small circuit breakers:

ABB SH200-D miniature circuit breaker SH202-D63: ?111.72 / only (price source, for reference only).

Schneider Osmart miniature circuit breaker: ?151.36 / only (price source, for reference only).

Siemens miniature circuit breaker 2P 63A household leakage protection switch: ? 179.9 / (price source, for reference only).

Delixi Electric Miniature Circuit Breaker (Miniature Circuit Breaker); DZ47LE-125 3P+N li(D) 100A: ?87.66/piece (price source, for reference only).

Second, the working conditions of the miniature circuit breaker

1) The ambient air temperature upper limit does not exceed +40 ° C, the lower limit is not lower than -5 ° C, and the average temperature value of 24 h does not exceed +35 ° C.

Note 1: The lower limit is -10 ° C or -25 ° C working conditions, the user must declare to the manufacturer when ordering.

Note 2: The user should consult with the manufacturer if the upper limit exceeds +40 ° C or the lower limit is lower than -25 ° C.

2) The altitude of the installation site should not exceed 2000m.

3), the relative humidity of the atmosphere does not exceed 50% when the ambient air temperature is +40 ° C, and higher relative humidity can be allowed at lower temperatures, for example, 90% at +20 ° C, occasionally due to temperature changes The condensation should be taken as appropriate.

4), pollution level: 2 levels.

5), installation categories: Class II and III.

6) The external magnetic field of the installation site should not exceed 5 times the earth's magnetic field.

7), generally vertical installation, tolerance of 2 ° in any direction.

8) There should be no significant impact or vibration at the installation.

Third, the working characteristics of small circuit breakers

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

2) Double wiring function, which can easily connect standard bus bars and flexible wires.

3), with finger-protection combination terminal block, higher security.

4) With energy storage mechanism operation, the contacts are quickly closed, which overcomes the adverse effects caused by the speed of the manual operation handle and improves the service life of the product.

5), a variety of accessories to choose from, and modular, flexible combination, user installation is very convenient.

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

7), high current limiting coefficient, superior performance and price ratio.

The above is the knowledge we have shared about small circuit breakers. The miniature circuit breakers are used more and more in our lives, and it is very important to protect our safety. Not only can he protect against circuit overload or short circuit, but also the infrequent operation of the circuit breaker under normal conditions. It is conceivable how powerful the miniature circuit breaker is. The above knowledge sharing of the miniature circuit breaker is also very detailed. I hope that our sharing can help everyone.
