摘要： A circuit interrupting device having a dual-coil solenoid for delivering an increased magnetic field to the solenoid plunger when a fault is detected and it is desired to place the device into a tripped condition. Independent switching devices control the flow of current through the respective coils of the solenoid and a third switching device controls the operation of the two coil driving switch devices. A detection circuit detects faults and controls the third switching device to activate the coil driving switching devices when a fault is detected. A programmable device runs a self-test program to determine whether the device is operating properly and faults can be detected. The programmable device can also independently control the operation of the two coil driving switching devices.

摘要： An auto-monitoring circuit including a first input structured to receive a signal from a processor of a circuit interrupter, a second input structured to receive power from a circuit protected by the circuit interrupter, a first switch structured to remain closed while the signal is received at the first input and remains above a predetermined threshold level and to open when the signal ceases to be received at the first input or drops below the predetermined threshold level, a second switch structured to remain open while the first switch is closed and to close when the first switch opens, and an output electrically connected to a trip circuit of the circuit interrupter. Closing the second switch causes a trip signal to be output to the trip circuit that causes the trip circuit to trip open the separable contacts.

摘要： A circuit breaker includes at least one coil for measuring electric current of an electrical conductor of an electrical circuit, connected to a control unit which compares the measured current or its equivalent with a first current limit value. Upon the first current limit value being exceeded, the control unit initiates an interruption of the electrical circuit. The two terminals of the coil are connected via a series circuit which has a first switch opened in its basic state, a voltage source and a voltage indicator. The control unit is designed such that, when a second current limit value is undercut and a first period of time is exceeded, the first switch is closed for a second period of time, the voltage indicator compares the voltage present with a first voltage value and, when the latter is exceeded, delivers information on the absence of faults of the coil.

摘要： The invention relates to a method for evaluating the mechanical performances of a switchgear device comprising at least one pole. Each pole comprises: a pair of contacts (12, 14); a support arm (16) for a first contact (14); a mechanism (22) for driving the support arm (16) comprising a rotary poles shaft (20) and energy accumulation means capable of driving a movement of the said arm in order to place the contacts (12, 14) in an open position. The method consists in: measuring the angle of rotation (θ) of the poles shaft (20) over a period of opening the contacts (12, 14); retrieving from the measurements at least one specific value; comparing the said specific value with specific initial operational specifications of the switchgear device; diagnosing the mechanical wear performances of the drive mechanism (22) as a function of a comparative state between the specific values obtained and those of the operational specifications.
