Electrical Schematic – Motor Protection – Against Overloads – Multifunctional Relay

Electromechanical or electronic relays protect the motor using the current flowing into the motor. The are perfectly suitable for regular operation.
However, they are not able to take into consideration multiple potential problems due to voltage temperature or specific application. Furthermore user’s requirements as maintenance or production management has become a major concern and electrical manufacturers has introduced to the market new products which can be tailored to the application and offer a global protection for the motor and the driven load.
