Adjustable Mccb WLM6RT-630A-3300 3P WLM6RT Series thermal magnetic type 400V/690V mccb 630A 3 Poles
Rated Current : 630A Number Of Poles : 3P / 4P Rated Working Voltage : 400V/690V
Advantages of Adjustable Type of MCCB
The load adjustable feature allows the MCCB to be fine-tuned to the actual load requirements of the electrical system. By adjusting the overload settings, the MCCB can cater to different levels of current flow without compromising its protective functions. This means that the MCCB can adapt to both normal variations in load and unexpected surges, providing consistent and reliable protection for the connected equipment.
