Electrical switching device and associated configuration and diagnostic methods

An electrical switching device comprising at least two connection lands, a measurement device configured for measuring a first electrical quantity of an electrical current flowing between the two connection lands, an electrical power supply system designed to deliver a first electrical power supply current, a trigger module and a switching member designed to switch between a first position electrically connecting the two connection lands and a second position wherein the two connection lands are electrically disconnected from one another, the trigger module comprising:

• a first memory for storing first values of detection parameters,
• a first driver module configured for detecting an electrical fault as a function at least of values measured by the measurement device and of the first stored values and for generating, in response, a switching signal for the switching member, and
• a communications module comprising a second memory which is non-volatile, the communications module being configured for receiving, via radiofrequency communications, a configuration signal containing second values of the detection parameters and for storing the second values received in the second memory,
• wherein the trigger module further comprises a second driver module configured for replacing, in the first memory, the first values by the second values, and
• wherein the first driver module is configured for comparing a second electrical quantity of the first electrical power supply current with a threshold and for controlling the supply of electrical power to the second driver module if the second electrical quantity is greater than or equal to the threshold,
• the electrical switching device further comprising a triggering device and a circuit breaker, the triggering device comprising a housing accommodating the trigger module, the circuit breaker comprising a housing accommodating the switching member, the housings of the triggering device and of the circuit breaker being distinct from one another.

A method for configuring a switching device comprising at least two connection lands, a measurement device configured for measuring an electrical quantity of an electrical current flowing between the two connection lands, an electrical power supply system designed to deliver a first electrical power supply current, a trigger module and a switching member designed to switch between a first position electrically connecting the two connection lands and a second position wherein the two connection lands are electrically disconnected from one another, the trigger module comprising:

• a first memory wherein first values of detection parameters are stored,
• a first driver module configured for detecting an electrical fault as a function at least of values measured by the measurement device and of the first stored values and for generating, in response, a switching signal for the switching member,
• a communications module comprising a second memory which is non-volatile, and
• a second driver module,
• the method comprising steps of:
• receiving second values of the detection parameters, via radiofrequency communications, by the communications module,
• storing the second values in the second memory,
• comparing, by the first driver module, a second electrical quantity of the first electrical power supply current with a threshold, and
• if the second electrical quantity is greater than or equal to the threshold, controlling, by the first driver module, the supply of electrical power to the second driver module and replacing, in the first memory, by the second driver module, the first values by the second values,
• wherein, if the second electrical quantity is strictly less than the threshold, there is an absence of supply of electrical power to the second driver module and the first driver module waits for the second electrical quantity to be greater than the threshold.
