Motors experience a high inrush current at the moment of energization, which can cause contact welding When de-energized, there is a reverse electromotive force(EMF) that, when combined with the supply voltage, acts on the contacts and can increase the arcing time, leading to accelerated contact wear. It is essential to select products that have motor load certifications. The relay requires obtained HP load certification.
