N Interrupting - Lug Line/ Load Side Connection
Features:
The traditional system used for this purpose is based on three different devices: a circuit breaker for protection against short-circuit, a thermal relay for protection against overload and phase loss or unbalance of phase, and a contactor for motor switching. In particular, when selecting these devices, different factors must be taken into consideration, such as:
The motor power
The diagram and type of starting
The type of motor: with cage rotor or with wound rotor
The fault current at the point of the network where the motor is installed
