This is a critical feature for such devices, especially in industrial environments where hazardous conditions may exist. Due to various unpredictable factors during operation—such as overloads, voltage fluctuations, frequent switching, short circuits, and imbalanced loads—the control systems are put under significant stress. If the on-off capability of the equipment is insufficient, it can lead to internal arcing or overheating inside the explosion-proof enclosure, which may result in damage or even dangerous accidents.
Unfortunately, many manufacturers overlook this aspect, using low-quality components that don't meet the necessary performance standards. This can lead to component failure, fires, or other serious incidents. Therefore, when selecting these components, it's essential not only to consider derating but also to have a clear understanding of the motor's load characteristics and operational requirements. With proper attention and thorough evaluation, such issues can be effectively avoided.
