Abstract:
The present invention provides a remote operable over-current protection apparatus. The apparatus includes control circuitry integrally arranged on a current path and a micro electromechanical system (MEMS) switch disposed on the current path, the MEMS switch responsive to the control circuitry to facilitate the interruption of an electrical current passing through the current path. The apparatus further includes a communication connection in signal connection with the control circuitry such that the control circuitry is responsive to a control signal on the communication connection to control a state of the MEMS switch.
Abstract:
A motor starter is provided. The motor starter includes micro-electromechanical system switching circuitry. The system may further include solid state switching circuitry coupled in a parallel circuit with the electromechanical switching circuitry, and a controller coupled to the electromechanical switching circuitry and the solid state switching circuitry. The controller may be configured to perform selective switching of a load current from a motor connected to the motor starter. The switching may be performed between the electromechanical switching circuitry and the solid state switching circuitry in response to a load current condition appropriate to an operational capability of a respective one of the switching circuitries.
Abstract:
The present invention comprises a method for over-current protection. The method comprising monitoring a load current value of a load current passing through a plurality of micro-electromechanical switching system devices, determining if the monitored load current value varies from a predetermined load current value, and generating a fault signal in the event that the monitored load current value varies from the predetermined load current value. The method also comprises diverting the load current from the plurality of micro-electromechanical switching system, devices in response to the fault signal and determining if the variance in the load current value was due to a true fault trip or a false nuisance trip.
