Overload Relay - L& T, SCHNEIDER An overload relay is an electrical safety device that protects motors and other equipment from damage caused by excessive current or overheating. It senses the current flowing through the circuit and trips the circuit if the current exceeds a predetermined limit, preventing the motor from overheating and potentially burning out. An OLR, or Overload Relay, is an electrical device designed to protect motors and other electrical equipment from overheating and damage caused by excessive current. Its primary purpose is to monitor the current flowing through a circuit and disconnect the power supply if the current exceeds a predetermined limit, preventing potential harm to the equipment. The main function of a relay is to control a high-power circuit using a low-power signal. Relays act as switches that can be opened or closed by an electrical signal, allowing for the remote control of power circuits, like motors or lights, from a distance. If a motor draws too much current and generates too much heat it indicates running in overload. Once a motor runs in overload for an extended period the extreme heat might destroy a motor's delicate A relay operates on the principle of electromagnetic attraction. When an electrical signal energizes a coil, it creates a magnetic field that attracts a metal armature, causing it to move and switch contacts. This movement either opens or closes a circuit, allowing the relay to control the flow of electricity based on the input signal. #olr #sparkelectric #schneider
