Does the overload relay turn the motor off? Customer is not sure how his LC1D12 contactor and LRD1516 overload work.
The overload does not directly turn the motor off. The overload current opens a set of control contacts within the overload relay. These contacts are wired in series with the starter coil in the control circuit of the magnetic starter. Breaking the coil circuit causes the starter contacts to open, disconnecting the motor from the line.
