RMW45 (RMW1/CW1/RMW1/CDW1/DW45) series of intelligent framework breaker

1, Purpose and scope

RMW45 (DW45, CW1, RMW1) series universal low-voltage circuit breaker (hereinafter referred breaker) suitable for AC 50HZ, rated voltage up to 660V (690V) and below, rated current 400A ~ 6300A of the power distribution network for the distribution of energy and protect circuits and power supply equipment from overload, under-voltage, short-circuit, single-phase ground fault hazards. Breaker with intelligent protection function, the selective protection precisely, can improve the reliability of power supply and avoid unnecessary power outages. With open communications excuse to four remotes, in order to meet the set requirements of the manufacturing centers and automation systems. At an altitude of 2000 meters, the breaker impulse withstand voltage 8000V (different altitudes according to the standard correction up to no more than 12000V). The circuit breaker without intelligent release and sensor can be used as an isolation labeled

Circuit breakers comply GB14048.2 "low-voltage switchgear and control voltage circuit breakers" and IEC947-2 "low-voltage switchgear and control equipment, circuit breakers" and other standards.

RMW1-6300A fixed Drawer (CW1-6300A fixed drawer);

3, normal working conditions and installation conditions

3.1 The ambient air temperature

The upper limit does not exceed +40 ℃, the lower limit is not lower than -5 ° C, 24H average of no more than +35 ° C;

Note: The lower limit is -10 ° C or -25 ℃ working conditions, the user should be affirmed and factory.

The working conditions of the upper limit of more than +40 ℃ lower than the lower limit - 10 ℃ -25 ℃, the user, in consultation with the factory.

3.2 installation site altitude does not exceed 2000M

3.3 atmospheric conditions

Relative atmospheric humidity in the ambient air temperature is +40 ℃ less than 50%, higher relative humidity at a lower temperature, a wet month average monthly maximum relative humidity of 90%, while the average minimum temperature for the month +25 ℃, and taking into account the condensation because of temperature changes on the surface of the product. Exceed the specified user should consult with the factory.

3.4 Protection class: IP30

3.5 use categories: Class B or Class A

3.6 Installation category

Rated working voltage 660V (690V) and below the circuit breaker undervoltage release, power transformer primary coil for Installation Category IV;

The auxiliary circuits few control circuit installation category III.

3.7 Installation conditions

The breaker should require the installation of this manual the the vertical measured slope of the circuit breaker does not exceed 5 degrees (mine is the inclination of the circuit breaker does not exceed 15 degrees)

4 Technical data and performance

4.1 rated current of the circuit breaker are shown in Table 1


4.2 breaker rated short-circuit breaking capacity and short-time withstand current (Table 2), the the the breaker arcing distance is zero (both circuit breaker arcing outside)


4.3 breaker maximum power of 360W. Breaker rated continuous current changes in ambient temperature are shown in Table 3.


The 4.4 intelligent overcurrent control protector features and functions

4.4.1 Over-current control and protection features

4.4.1.1 controller tuning values ​​Ir (I / in) and error in Table 4.


4.4.1.2 long delay inverse time current protection operating characteristics I2TL = (1.5Ir1) 2TL (1.05 ~ 2.0) Ir1 action time are shown in Table 5, the time error of ± 15%.

4.4.13 short delay overcurrent protection characteristics

Short delay overcurrent definite time, such as requiring low multiples inverse time characteristics: I2TS (8Ir1) 2ts, ts for general delay design time, when the overload current> 8Ir1 is, automatically converted to a definite time characteristics definite time characteristics are shown in Table 6. now the error is ± 15%.


4.4.1.4 overcurrent trip protection features shown in Figure 1, the ground fault protection features several Figure 2

4.4.2 M-intelligent over-current controller functionality

A. Ammeter Function

Each phase running current and ground leakage current, the maximum phase current display properly, you can also display the current value or the time value of the tuning, testing and fault.

B. voltmeter function

RMW45 (DW45 universal type breaker/DW45 intelligent circuit breaker) is now more popular universal type circuit breaker, mainly used for distribution network, the electric energy and protecting circuits for distribution, power supply and power equipment from overload, owe voltage, short circuit, the harm of grounding faults, and has a high accuracy of selective protection, improve the power supply reliability. But if the breaker selection or use undeserved, can cause error action or refuse to action, lose it should be up to protect, but reduce the reliability of power supply.
