Leakage circuit breaker RMM2L model purpose and wiring diagram

Use of leakage circuit breaker RMM2L

The plastic case circuit breaker with residual current protection is a derivative product of the RMM2 series. Its structure is based on the original RC type residual current release. Therefore, the okplazas.com leakage circuit breaker has the same RMM2 The same technical characteristics of the model circuit breaker, and the corresponding accessories can also be used together.

When the leakage circuit breaker is equipped with a residual current release, it can provide better protection for electrical fires and other hazards that may be caused by ground faults. The tripping characteristics of the residual current release are AC type, which can provide reliable tripping action to the AC sinusoidal current that is suddenly applied or slowly rising. The implementation standard is Chinese national standard GB14048.2 and is equivalent to IEC60947-2. .

3. The code of the three-pole circuit breaker is omitted, and the four-pole circuit breaker is represented by the number 4;

4.There is no code for toggle operation. Electric operation is indicated by letter P, rotating handle operation is indicated by letter XZ, and extended rotating handle operation is indicated by letter Z.

Leakage circuit breaker RMM2L installation conditions

◆The ambient air temperature cannot exceed +40℃ and cannot be lower than -5℃, and the average value within 24 hours should not exceed +35℃;

◆The altitude of the installation site is usually no more than two kilometers;

◆The pollution level is 3, and the leakage circuit breaker needs to be installed according to the requirements specified in the provided instructions;

◆The relative humidity of the atmosphere at the installation site cannot exceed 50% when the ambient air temperature is +40℃, and a higher relative humidity is allowed at a lower temperature;

Circuit breakers and accessories connected to the main circuit are used for overvoltage category III, and accessories that are not connected to the main circuit are used for overvoltage category II.

Accessories for leakage circuit breaker RMM2L

◆The method and performance of the equipment with various internal and external accessories are the same as the RMM2 model circuit breaker. The drawer type and plug-in installation are not suitable for RMM2L leakage circuit breakers. The CD electric operating mechanism is also not suitable for the 100A shell frame. Suitable for use on RMM2L leakage circuit breaker;

◆The residual current tripping device can provide the residual current tripping alarm function;

◆The residual reactance trip alarm switch is a normally open and one normally closed contact that is not electrically separated, and its electrical parameters are the same as those used by the RMM2 type circuit breaker of the same frame class;

◆According to special requirements, the residual current release can also send out an alarm signal only through the alarm switch to achieve the function of only alarming but not tripping.

Instructions for use of leakage circuit breaker RMM2L

1. The upper wiring terminal of the equipment is the power terminal, and the lower wiring terminal is the load terminal. Remember not to reverse the wiring.

2. The residual operating current and time of the residual current release should be adjusted by professional staff according to requirements.

3. After the residual current release of the leakage circuit breaker performs the tripping action, the reset button R on the panel will jump out, indicating that the tripping device of the device has been tripped. Before the circuit breaker reclosing, it is necessary to eliminate the leakage phenomenon and press the reset button R at the same time to reset the trip unit before closing the circuit breaker.

4. The trip unit should be inspected regularly (six months) to test whether the action is normal and reliable. Press the leakage circuit breaker test button T when the main circuit is energized, the non-delay type trip unit should be tripped immediately, if it is the time delay type, it will trip after the delay time is reached.

5.The rated working voltage of the residual current release is 400V/AC50Hz, and no external power supply is required. The lowest operating voltage is 50V (relative to ground), and the trip unit can also work in the case of any phase voltage failure.
