Motors are a significant investment and often run critical processes. Motor protection relays are used to protect the windings from damage due to electrical faults and thermal overloads. Adequate motor protection not only prevents motor damage, but also ensures optimal process efficiency and minimal interruption. Cost recovery when using a motor protection relay is achieved by extending the life of the motor, preventing motor rewinds and reducing downtime.
