DLF362 residual current operated circuit breaker

一、summarize
    DLF362 type residual current operated circuit breaker is designed according to the latest IEC61008-1 standard, and it also conforms to the standard of EN50022 on modular switching, that is, the switch can be installed on the standard guide rail of “hat shape” symmetrical structure.
    After the DLF360 residual current operated circuit breaker detects the ground fault current (leakage current), it compares with the leakage trip current value. When the fault current value is greater than the leakage trip current value, the circuit breaks the circuit breaker.
    The circuit breaker and the grounding system can protect the human body from indirect contact with the charged body. When the rated leakage current is greater than or equal to 30 mA, it can also be used as an additional protection against direct contact with the charged body.
    In addition to the direct or indirect contact with the function of live protection, the circuit breaker can also protect the possible fire hazard if the insulation is damaged.

二、scope of application
    DLF362 residual current operated circuit breaker without overcurrent protection (RCCB) meets GB16916.1, BS4293 and other standards, applicable to industrial and mining enterprises, commercial and home exchange 50-60Hz single-phase 240 (220V), three-phase 415V (38OV) As a personal electric shock and equipment leakage protection, it can be used as an infrequent conversion of the line under normal circumstances.

5, installation of pollution levels: Pollution Level II.
6, the installation type: the use of standard rail installation.
7. Installation conditions: The external magnetic field of the installation site should not exceed 5 times of the geomagnetic field. RCCB should generally be installed vertically. The handle should be turned on to the power supply position. The installation site should have no significant impact and vibration.
8. Connection mode: Use screws to press the wiring or use busbar wiring.

六、structure and working principle
1, structure
    The DLF362 residual current operated circuit breaker is mainly composed of a zero-sequence current transformer, a trip unit, an operating mechanism, a contact system, an extinguishing device, and an insulating housing.
2, the working principle
    When the line works normally, the residual current operated circuit breaker is in the closed position. When the line experiences electric leakage or electric shock, the signal output by the zero-sequence current transformer pushes the release action and cuts off the power within 0.1 seconds, thereby realizing the leakage protection function. .
3, the working principle diagram


七、 matters needing attention
1. The leakage protection characteristics of residual current operated circuit breakers are set by the manufacturer and cannot be disassembled during use.
2. After the residual current operated circuit breaker is used for a certain period of time (usually one month), it is necessary to press the test button once in the closed state to check whether the circuit breaker performance is normal and reliable (each time the test button is pressed, the circuit breaker should be able to Once broken, if it is out of order, it should be unloaded and sent to the manufacturer for repair.
3. Residual current operated circuit breakers shall not be subject to rain immersion during transportation, storage and use.
4, the residual current circuit breaker can not play a protective role in the short circuit.
