A switch fuse unit Switch Fuse Unit (SFU) combines two essential functionalities: a switch that enables the manual opening and closing of circuits and a fuse that provides overcurrent protection. This dual-purpose nature empowers users to isolate circuits during maintenance or emergencies and offers protection against overloads and short circuits. Switch Fuse Unit (SFU): FAQs … Read more
thermal overload relay [olr] is an electrical protection device designed to monitor and protect electric motors from overheating due to excessive current flow. It serves as a safeguard against the risks posed by motor burnouts, which can occur if motors operate for prolonged periods with elevated current levels. Overload Relay Types. These are classified into … Read more
