MCCB Highlights
In addition to Long-Time protection, the WLM6E MCCB also incorporates Short-Time protection, which is tailored to address short-duration overcurrent events. These transient overcurrents can occur during system disturbances or faults, and the Short-Time protection function of the MCCB is designed to swiftly interrupt the circuit to mitigate the impact of such events. By providing rapid and selective protection against short-duration overcurrents, the WLM6E MCCB helps minimize the risk of damage to the electrical system and its components.
