Usually, a complex control circuit is always composed of several basic control units or links. They are like building blocks. They are based on the function, production process and control requirements of electrical circuits and equipment. Control tasks are accomplished by designing organically together.
When troubleshooting, according to the fault phenomenon combined with the electrical schematic and control relationship, determine the possible unit or link of the fault, and then according to the connection characteristics of the main circuit, such as the reverse connection line, the step-down start star A triangle connection, a speed-regulating resistor or a frequency converter connection, a trigger connection of a thyristor, etc., may find a corresponding control device or control unit, and may also find a corresponding electrical appliance or unit according to a chain connection of the auxiliary point of the electrical appliance. Going further can determine the exact point of failure to identify the problem.
KNLN6-63 Residual Current Circuit Breaker With Over Load Protection
KNLN6-63 TWO FUNCTION : MCB AND RCCB FUNCTIONS
leakage breaker is suitable for the leakage protection of the line of AC 50/60Hz, rated voltage single phase 240V, rated current up to 63A. When there is human electricity shock or if the leakage current of the line exceeds the prescribed value, it will automatically cut off the power within 0.1s to protect human safety and prevent the accident due to the current leakage.
leakage breaker can protect against overload and short-circuit. It can be used to protect the line from being overloaded and short-circuited as wellas infrequent changeover of the line in normal situation. It complies with standard of IEC/EN61009-1 and GB16917.1.
