What are the models of the cm1 breaker? Cm1 circuit breaker use conditions

In the production of our lives, some small products can always bring great functions to our lives and work. It seems to be small, but it can be widely used in various fields of electronics and industry, cm1 circuit breakers. One is mainly installed in a low-voltage configuration of the electric cabinet, which is used to operate the main switch's switch circuit breaker. Its control and protection power distribution functions are widely used by the circuit network. Then, what are the models of the cm1 circuit breaker? What is the condition for its use?

First, CM1 circuit breaker model

The CM1 switch circuit breaker is mainly installed in the low-voltage power distribution cabinet as a main switch for controlling and protecting the power distribution network. Its technical performance has reached the international advanced level of similar products in the 1990s. It complies with IEC947-2 and GB14048.2 "Low Voltage Circuit Breaker" standards. The model cm1 breaker model is as follows:

16 RMC1/C16RMC1-2/C16RMC1-3/C16RMC1-4/C16

20RMC1/C20RMC1-2/C20RMC1-3/C20RMC1-4/C20

63RMC1/C63RMC1-2/C63RMC1-3/C63RMC1-4/C63

Second, the conditions of use

1. The ambient air temperature is -5 °C ~ +40 °C, and the average value of 24h does not exceed +35 °C (except for special order).

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

3. The relative humidity of the air does not exceed 50% at the highest temperature of +40 °C; the higher relative humidity can be obtained at lower temperatures, and the monthly minimum temperature of the wettest month does not exceed +25 °C. The monthly average maximum relative humidity does not exceed 90%, and the condensation on the surface of the product due to temperature changes is considered.

4. The pollution level is level 3.

Introduction to the structural characteristics of the three-cm1 circuit breaker

Contact system

Each phase contact is mounted in an insulated chamber. The contact system adopts a structure in which a plurality of contacts are connected in parallel, which reduces the inertia of the contact system and ensures the high breaking capacity of the circuit breaker.

2. Operating mechanism

Installed in the center of the circuit breaker, isolated from the main circuit; the circuit breaker is closed by the spring energy storage mechanism, and the closing speed is fast. The operating mechanism has both electric and manual energy storage, closing and disconnection. All accessories are common throughout the series.

3. Drawer seat

Shake the handle on the lower beam of the drawer seat to realize the three working positions of the circuit breaker (the position indication is next to the handle); the "connection" position: the main circuit and the secondary circuit are both connected, and the isolation plate is opened; the "test" position : The main circuit is disconnected. It is separated by an insulating spacer and only the secondary circuit is turned on. The necessary action test can be performed; the "separation" position: the main circuit and the secondary circuit are all disconnected, and the isolation plate is closed.

4. Drawer type circuit breaker has reliable mechanical interlocking device, which can only make the circuit breaker close in the connection position and test position; the circuit breaker has 47 secondary circuit terminals; the same rated current drawer circuit breaker (including the body) It is interchangeable with the drawer.

The above is the knowledge about the model and the conditions of use of the cm1 circuit breaker introduced by Xiaobian. I hope to help you.
