Most electrical circuits need protection due to the high value of electric current that they carry. In larger networks, it is important that the circuit is protected from these surges because otherwise there is a chance that the whole network can be blown off. Schneider over Load relays are economic electro-mechanical protection devices for the main circuit. They offer reliable protection for the motors and different equipment in the circuit. In the event of an overload or a phase failure, they can effectively cut off the circuit and then be used to protect the entire network.
