Model CKCM1L - **0 - m / **0 b

The number of 4 p

Rated frequency *0 ~ *0 (Hz)

The rated insulation voltage (**0 V)

Trip current **0 (A)

Product certification CCC

Fixed installation way Speed of fast Arcing medium air type Structure of the plastic shell Operation manual Scope of application :

CKCM1 series with residual current protection plastic shell type circuit breaker (hereinafter referred to as circuit breaker), is the company adopts the international advanced design and manufacturing technology development, the development of one of the new type of circuit breaker. The rated insulation voltage **0 v, and applied to ac *0 hz, rated voltage **0 v, rated current **0 a circuit is not frequent conversion and motor are not frequent starting.

Circuit breaker with overload, short circuit and low voltage protection function, can protect circuit and power equipment from being damaged, as well as over current protection can not be detected long-standing ground fault may cause fire danger to provide protection.

Circuit breaker according to its rated limit short circuit breaking capacity (lcu) of high and low is divided into M type (higher), H (high marks broken) category. The circuit breaker has small volume, high breaking, fly short arc, resistance to vibration, etc.

The circuit breaker can be installed vertically (that is, vertical pack), can be installed horizontally (that is, the horizontal loading). The circuit breaker shall not fall into line. The only allow.

The circuit breaker products perform the following standards:

The general and GBT****8.1 IEC***********0 IEC******2 and low voltage circuit breaker and appendix B GBT****8.2 circuit breaker with residual current protection IEC******4 and GBT****8.4 contactor and motor starter IEC******5.1 and GBT****8.*1 electromechanical control electric circuit

The main features: Routine residual current circuit breaker leakage protection mode of power supply for two-phase sampling, the series circuit breaker for the three-phase, if lack of Ren Yixiang, circuit breaker leakage protection module can still work normally;Rated residual current action I delta n and biggest turn-off time according to the actual situation field can be adjusted when the phase voltage down to *0 v, leakage protection module can still work normally. With leakage alarm output function; Conform to the requirements of the elevator compatible IEC****7 appendix B;

Overall dimensions, the installation size is the same as CM1 series circuit breaker specifications, installation has good compatibility.

Applicable to the work environment: At an altitude of ***0 m and the following; Surrounding medium temperature is not higher than + *0 ℃ and not lower than 5 ℃, *5 ℃ and average no more than *4 h + (special orders except);

Installation site of air relative humidity when the highest temperature is + *0 ℃ not more than *0%, at a lower temperature can have higher relative humidity, the wettest month average minimum temperature is not more than + *5 ℃, the mean monthly maximum relative humidity is not more than *0% of the month, and considering the temperature changes occur in the condensation on the surface of the product; Pollution level 3;

Circuit breakers for main circuit installation category â…¢, not connected to the main circuit of the auxiliary circuit and control circuit, installation category for â…¡;

Circuit breaker shall be installed in the explosion danger and non conductive dust, enough to a corrosive action on metals, and damage the insulation; Circuit breaker shall be installed where there is no rain and snow hit. Circuit breaker shall be installed according to the product specification.
