Product Details

WLM6RT Adjustable Type of MCCB Functions

The adjustable type of MCCB is designed to offer flexibility in its protective functions. One of its key functions is the ability to adjust the overload settings. This feature allows the MCCB to be tailored to the specific needs of the electrical system it is protecting. The overload settings typically include 0.7ln, 0.8ln, 0.9ln, and 1.0ln, where “ln” represents the rated current of the MCCB. By being able to adjust the overload settings, the MCCB can provide optimal protection for the connected electrical equipment and prevent unnecessary tripping during normal fluctuations in current.

In addition to overload protection, the adjustable type of MCCB also offers instantaneous protection with adjustable settings. Instantaneous protection is crucial for rapidly detecting and interrupting short-circuit faults. The adjustable instantaneous protection settings, such as 7ln, 8ln, 9ln, and 10ln, allow for precise calibration based on the specific requirements of the electrical system. This level of customization ensures that the MCCB responds swiftly to short-circuit faults while minimizing the risk of nuisance tripping.
